An object moves along a straight line with an acceleration of 2 m/s2. If its initial speed is 10 m/s, what will be its speed 2 s later?

An object dropped from a cliff falls with a constant acceleration of 10 m/s2. Find its speed 5 s after it was dropped.

The displacement equation of a particle moving along a straight line with uniform acceleration is x = v_0t + 1/2at^2 . Find the distance covered by the particle in the last second of its motion.

The initial velocity of a particle moving along straight line is 20 m/s and its retardation Is 2 m/s_2. The distance moved by the particle in the fifth sec. of its motion is :

An object is moving along a straight line with a uniform speed of 10m/s. Plot a graph showing distance versus time from t=0 to t=10s.

Find the force needed to produce an acceleration of 6 m/s2 in a ball of mass 4kg.

What is the S.I. unit of speed?

A monkey of mass 40 kg climbs on a rope (Fig. 5.20) which can stand a maximum tension of 600 N. In which of the following cases will the rope break: the monkey (a) climbs up with an acceleration of 6 m s^2 (b) climbs down with an acceleration of 4 m s^2 (c) climbs up with a uniform speed of 5 m s^1 (d) falls down the rope nearly freely under gravity? (Ignore the mass of the rope).

A stone is thrown in a vertically upward direction with a velocity of 5 m s^1 . If the acceleration of the stone during its motion is 10m s^-2 in the downward direction, what will be the height attained by the stone and how much time will it take to reach there?
