CAIE A-Level Physics AS 3.3.2 The Principle of Conservation of Momentum to Solve Simple Problems Questions question 1

[Maximum number: 1]

A lead pellet is shot vertically upwards into a clay block that is stationary at the moment of impact, but is able to rise freely after impact.

Figure for Question CAIE A-Level Physics AS 3.3.2 The Principle of Conservation of Momentum to Solve Simple Problems Questions question 1 — CAIE A-Level Physics AS

The mass of the pellet is 5.0 g and the mass of the clay block is 95 g .
The pellet hits the block with an initial vertical velocity of 200 m s−1200 \mathrm{~m} \mathrm{~s}^{-1}. It embeds itself in the block and does not emerge.

How high above its initial position will the block rise?

A

5.1 m5.1 \mathrm{~m}

B

5.6 m

C

10 m

D

100 m
