Test: Average Velocity & Average Speed - Question 1

Which of the following statements are incorrect?
(i) Average velocity is path length divided by time interval.
(ii) In general, speed is greater than the magnitude of the velocity.
(iii) A particle moving in a given direction with a non-zero velocity can have zero speed.
(iv) The magnitude of average velocity is the average speed.

Detailed Solution for Test: Average Velocity & Average Speed - Question 1

A particle moving in a given direction with non-zero velocity cannot have zero speed. In general, average speed is not equal to magnitude of average velocity. However it can be so if the motion is along a straight line without change in direction.

Test: Average Velocity & Average Speed - Question 2

A car is moving along a straight line OP as shown in the figure. It moves from O to P in 18 s and returns from P to Q in 6 s. Which of the following statements is not correct regarding the motion of the car? 

Detailed Solution for Test: Average Velocity & Average Speed - Question 2

From O to P and back to Q

From O to P and come back to O

Test: Average Velocity & Average Speed - Question 4

A cyclist moving on a circular track of radius 40m completes half a revolution in 40s. Its average velocity is

Detailed Solution for Test: Average Velocity & Average Speed - Question 4

Test: Average Velocity & Average Speed - Question 5

The position of an object moving along x-axis is given by x = a + bt2 , where a = 8.5 m and b = 2.5 m s−2 and t is measured in seconds. The average velocity of the object between t = 2 s and t = 4 s is

Detailed Solution for Test: Average Velocity & Average Speed - Question 5

 

Given: a= 8.5 m
            b=2.5ms−2
Position is given as,
x=a+bt2 …(1)

 

At t= 2 s, equation. (1) becomes,
x= a + b(2)2
→ x= a +4 b

Substituting the values in above equation we get,
x= 8.5 + 4 × 2.5
⇒ x= 18.5m

 

At t= 4 s, equation. (1) becomes,
x= a+b (4)2
→ x= a +16b
Substituting the values in above equation we get,
x= 8.5+16 × 2.5
⇒ x= 48.5m

 

Displacement from t= 2 s to t= 4 s is given by,
S21 = x3−x2
Substituting the values in above equation we get,
S= 48.5–18.5
⇒ S1 = 30m

 

Time taken by the object to move from x2 to x3 is given by,
t′′ = 4−2
⇒ t′′ = 2s 
Therefore, the average velocity of object is given by,
V= S2 / t′′
Substituting the values we get,
V= 30 / 2
⇒V2= 15m/s

So, Option (c) is the correct answer.
