Motion In A Straight Line Mock Tests

A car moving with speed v on a level road applies brakes and comes to rest after traveling distance d. If the same car moves with speed 3v and applies the same brakes, the stopping distance will be:

A body is projected vertically upward with initial velocity u. The maximum height reached is:

A body is projected vertically upward with velocity 100 m/s. The time after which it returns to the ground is approximately: (g = 10 m/s²)

A car starts from rest and moves with uniform acceleration of 2 m/s². The distance covered in 5 seconds is:

A particle moves along a straight line such that its position x (in metres) at time t (in seconds) is given by x = 3t² − 2t + 1. The instantaneous velocity of the particle at t = 2 s is:

A car travels half the distance at speed v₁ and the remaining half at speed v₂. The average speed for the entire journey is:

A particle moves along a straight line such that its position at time t is given by x(t) = 6t² - 2t³ meters. The velocity of the particle at the instant when its acceleration is zero is:

A particle moves such that its position vector is given by r⃗ = (3t² + 2t)î + (4t - t³)ĵ. The acceleration of the particle at t = 2 s is:
