QUESTION 12

A cannonball is launched with initial speed 56 m/s, and hits a target at speed 35 m/s. Which of the following is correct?
The target was higher than the cannon
O The target was below the height of the cannon
O The target was at the same height as the cannon

Answer 1

The target was higher than the cannon

Step-by-step explanation:

Given that a cannon ball is launched with initial speed 56 m/s, and hits a target at speed 35 m/s.

The initial velocity must be 56 m/s, while the final velocity will be 35 m/s.

When an object is thrown upward with an initial velocity, the object continues to move upwards with decreasing in magnitude of velocity till it reaches the maximum height where the final velocity will be equal to zero.

In this question, since the final velocity is less than the initial velocity, we can conclude that the target is higher.

Therefore, the target was higher than the cannon.
