Jason launches a model rocket with a mass of 2.0 kg from his spring-powered rocket launcher with a spring constant of 800 n/m. he pulls it back .55 m. if jason aims it straight up, what potential energy will the rocket have when it reaches its maximum height? what height will it reach?

121 Joules

6.16717 m

Explanation:

m = Mass of the rocket = 2 kg

k = Spring constant = 800 N/m

x = Compression of spring = 0.55 m

Here, the kinetic energy of the spring and rocket will balance each other

The initial velocity of the rocket is 11 m/s = u.

v = Final velocity

s = Displacement

a = Acceleration due to gravity = 9.81 m/s² = g

The maximum height of the rocket will be 6.16717 m

Potential energy is given by

The potential energy of the rocket at the maximum height will be 121 Joules

you go to your settings preference and in the end youll see sth that says "i want to delete my acc" click on it and u'll acc will be deleted but u have to wait.

the answer is mosques. they are an important part of islamic culture.
