Question
A student launches a rocket with some initial velocity v at some angle 8. The rocket hits a wall on its way back down to the ground. (See the diagram below.) Which of the following statoments is most accurate? The speed of the rocket just before it hits the wall is equal to the starting speed of the rocket The speed of the rocket just before it hits the wall is less than the starting speed of the rocket The speed of the rocket just before it hits the wall is greater than the starting speed of the rocket More information is needed as the speed of the rocket before it hits the wall depends on the mass of the rocket
Explanation / Answer
The speed of the rocket just before it hits the wall is greater than the starting speed of the rocket.
because the impact speed is more while coming with certain height which is more than the starting point.
