Motion Compulsory Test Class 9 - Question 3

A body moving from rest with uniform acceleration travels a distance X in the first t seconds and travels a distance Y with same acceleration in the next 2t seconds, then

Detailed Solution for Motion Compulsory Test Class 9 - Question 3

For a body at rest, u = 0. Thus, we have

S = 1/2 at2

X = 1/2 at2

Y = 1/2 a (2t)2

= 1/2 a * 4t2

Y = 4x 

Motion Compulsory Test Class 9 - Question 4

If a moving body comes to rest, then its acceleration is-

Motion Compulsory Test Class 9 - Question 5

The equations of motion can be derived by using

Detailed Solution for Motion Compulsory Test Class 9 - Question 5
The First Equation of Motion. Consider an object moving so that its velocity-time graph is a straight line. Such an object is undergoing constant acceleration, since the slope of the graph is constant. The first equation of motion gives the final velocity after a time t for these objects, given an initial velocity v0 .
Motion Compulsory Test Class 9 - Question 6

The third equation of motion is

Motion Compulsory Test Class 9 - Question 7

A plank with a box on it at one end is gradually raised about the other end. As the angle of inclination with the horizontal reaches 30o, the box starts to slip and slides 4.0 m down the plank in 4.0 s. The coefficients of static and kinetic friction between the box and the plank will be respectively

Detailed Solution for Motion Compulsory Test Class 9 - Question 7

Given a plank with a box on it one end is gradually raised about the end having angle of inclination is 300, the box starts to slip and slides down  4 m the plank in 4 s as shown in a figure.


Thus, coefficient of kinetic friction between the box and the plank is 0.51

Motion Compulsory Test Class 9 - Question 8

A cat runs around the boundary of a square field of side 6m in 10s. The displacement of the cat in 1 minute is

Detailed Solution for Motion Compulsory Test Class 9 - Question 8
After running around the boundary of the square field, the cat reaches the same spot thus the displacement of the body is zero.
Motion Compulsory Test Class 9 - Question 9

The area under the speed-time graph gives the -----

Motion Compulsory Test Class 9 - Question 10

 

Motion Compulsory Test Class 9 - Question 11

An athlete uniformly increases his speed from rest at the rate of 1m/s2 .The time taken to complete 200m race is:

Motion Compulsory Test Class 9 - Question 12

For a body starting from rest and moving with uniform acceleration, the ratio of the distances covered for 1s,2s,3s… is

Detailed Solution for Motion Compulsory Test Class 9 - Question 12
we need to use the formula, S = ut+(1/2)at^2, but initial velocity u = 0, hence S = (1/2)at^2
 
Distance covered in 1 sec S1 = (1/2)a ;
Distance covered in 2 sec S2 = (1/2)ax4  ;
Distance covered in 3 sec S3 = (1/2)ax9  ;
 
S1:S2:S3 = 1:4:9
Motion Compulsory Test Class 9 - Question 13

 

Motion Compulsory Test Class 9 - Question 14

Area under v-t graph represents a physical quantity which has the unit:

Motion Compulsory Test Class 9 - Question 15

Name the instrument used to measure instantaneous speed of vehicle

Motion Compulsory Test Class 9 - Question 16

If you move 5km north, 5km east and 5km south, then your displacement is

Detailed Solution for Motion Compulsory Test Class 9 - Question 16

Total displacement 5km towards east.

Motion Compulsory Test Class 9 - Question 17

The ratio of CGS to MKS unit of acceleration is 

Detailed Solution for Motion Compulsory Test Class 9 - Question 17

C.G.S unit of acceleration = 1 cm/s2

M.K.S. unit of acceleration = 1m/s2

C.G.S unit of acceleration/ M,K.S unit of acceleration =

1cm/s2 / 1m/s2

= 1cm / 100 cm

= 1/100

=1:100

Motion Compulsory Test Class 9 - Question 18

If a train is travelling due north and its braked are applied, it will have?

Motion Compulsory Test Class 9 - Question 19

A car increases its speed from 20km/h to 40km/h in 10 seconds. Its acceleration is

Motion Compulsory Test Class 9 - Question 20

If the speed-time graph is a straight line parallel to the time axis, then the body is 

Detailed Solution for Motion Compulsory Test Class 9 - Question 20
Speed-time graph is a straight line parallel to time axis, it means that the speed of the object is not changing with time i.e., the object is performing uniform motion.
