(a) Define speed and velocity such that the two may be distinguished. An object moves with
an initial velocity of 4ms-1 . If it moves with a uniform acceleration of 2ms-2 find the
displacement after 20 s. (4-marks )
(b) A body moving with a constant acceleration reach the velocity 4ms-1 after 10s. If the
body start from rest , find the velocity after (a) 12s (b) 14s (c) 16s (d) 18s. Draw the
velocity time graph for the interval 10 s to 18 s. From the graph , find the velocities at
8s and 20s. (4marks )
P.T.O →
- (a) State law of conservation of momentum. ( 4 marks )
A 30g bullet moving at a constant velocity hits a wooden block of mass 3kg and continues
to travel at the velocity of 2 ms-1 together with the block. What is the velocity of the bullet
when it hits the block?
