An air rie pellet of mass 2.0g is red horizontally at
a block of clay of mass 50g that rests on a frictionless
horizontal surface. The pellet passes through the
block with no change in the direction of motion and
emerges with a speed of 150ms 1
. Immediately aer
the pellet emerges from the block, the block is
moving at a speed of 2.4ms−1
a. Calculate the initial speed of the pellet.
b. It takes 1.5 × 10−4
s for the pellet to travel through
the block.
Calculate:
i. the average acceleration of the pellet
ii. the average force between the pellet and
the block.
