Rocket Height A rocket, initially at rest on the ground, accelerates straight up

Question

Rocket Height A rocket, initially at rest on the ground, accelerates straight upward from rest with constant net acceleration a, until time t1, when the fuel is exhausted. Find the maximum height H that the rocket reaches (neglecting air resistance). Express the maximum height in terms of a, t1, and/or g. Note that in this problem, g is a positive number equal to the magnitude of the acceleration due to gravity. If the rocket's net acceleration is a = 3g for t1 = 5.00 s, what is the maximum height the rocket will reach? Express your answer numerically in meters, using g = 9.81 m/s2.

Explanation / Answer

H= .5*a*t1^2 B) H3 = .5*a*t1^2 putting values,, =.5*3*9.81*5^2= 367.875 m
