Question

Alexis shoots a toy rocket straight upward from the ground. When the rocket is 17.5m
from the ground, it runs out of fuel. The instant the toy rocket runs out of fuel it has a
speed of 13.5m/s and is in Freefall. (NOTE: While the rocket rises to 17.5m, it is not in
Freefall. The rocket is only Freefall immediately after it runs out of fuel.)
(HINT: Think about what your initial information should be to start this problem when
the rocket is in a state of Freefall)
A ) Determine  the two velocities of the toy rocket when it is 21.0m from the ground,
B) the two times it takes for the toy rocket to be 21.00m from the ground,
C)the time it takes for the toy rocket to reach the ground from where it runs out of
fuel,

D) the average velocity of the toy rocket from when it runs out fuel to the moment
before it reaches the ground

Expert Solution
Check Mark
Step 1: Determine the given data:

straight h equals 17.5 space straight m
straight H equals 21.0 space straight m divided by straight s
straight u equals 13.5 space straight m divided by straight s
