Motion — Set 4

Which graph represents uniform motion (constant velocity) in a distance–time plot?

A runner completes 400 m in 50 s. What is the average speed?

Instantaneous speed is the speed?

A wheel rotates at 120 rpm. What is its angular speed in rad/s? (Take π ≈ 3.14)?

In uniform circular motion, the acceleration of a particle is directed?

A body moves with uniform acceleration from rest and reaches 12 m/s in 6 s. How much distance does it cover in this time?

Which equation is correct for displacement in uniformly accelerated motion?

A body covers 100 m in 5 s starting from rest with uniform acceleration. What is the acceleration?

In free fall from rest (no air resistance), the distances covered in successive equal time intervals are in the ratio?

A projectile is thrown with speed 20 m/s at 45°. Taking g = 10 m/s^2, what is its range?
