Motion

If air resistance is taken into account for a ball thrown upwards, the time of ascent is ______ the time of descent.

What is the magnitude of acceleration for an object moving with velocity v = 5t^2 + 2t at t = 1s?

A body is dropped from a height H. The time taken to cover the second half of the height is:

If a body travels with uniform acceleration, the graph of 'v^2' against 's' is a:

A train 100m long is crossing a bridge of length 200m at a speed of 72 km/h. The time taken is:

The velocity of a body is doubled. Its acceleration will be:

A bird flies 100m North, then 100m South. Its average velocity is:
