The relation between time and distance is t = αx2 + βx,where α and β are constants. The retardation is given by:
A car moves in a straight line such that for a short time its velocity is defined by V = (3t2 + 2t) m/s, where 't’ is in seconds, Determine its position when t = 3 sec.

For the point moving on a straight line which of following is true.
Two bodies of mass m1 and m2 are dropped from different heights h1 and h2 respectively. Neglecting the effect of friction, the ratio of times taken to drop thought the given heights would be
For the point moving on a straight line which of following is true.
For the point moving on a straight line which of following is true.
There are two points P and Q on a planar rigid body. The relative velocity between the two points
A car is moving with uniform acceleration covers 450 m in a 5 second interval and further it covers 700 m in a 10 second interval. The acceleration of the car is
A point mass is shot vertically up from ground level with a velocity of 4 m/s at time, t = 0. It loses 20% of its impact velocity after each collision with the ground. Assuming that the acceleration due to gravity is 10 m/s2 and that air resistance is negligible, the mass stops bouncing and comes to complete rest on the ground after a total time (in seconds) of
