Motion in a Straight Line

What is the SI unit of velocity?

A car moves with a uniform velocity of 20 m/s. What is its acceleration?

If a body starts from rest and moves with a uniform acceleration of 5 m/s², what will be its velocity after 4 seconds?

A particle moves along a straight line with displacement x = 4t² + 3t, where x is in meters and t in seconds. What is the velocity at t = 2 s?

Which of the following graphs represents uniform acceleration?

A body covers distances of 10 m, 30 m and 50 m in the 1st, 2nd and 3rd seconds respectively. What is its acceleration?

A stone is thrown vertically upwards with velocity 20 m/s. How long does it take to reach the highest point? (Take g=10 m/s²)

A car accelerates uniformly from rest to 36 km/h in 10 seconds. What is its acceleration in m/s²?

The displacement of a particle is given by s = 3t³ - 5t² + 2t (s in meters, t in seconds). What is the acceleration at t = 2 s?
