Homework Statement
Pam has a mass of 40.0kg and she is at rest on a smooth level frictionless ice. pam straps on a rocket pack. the rocket pack supplies a constant force for 22.0m and pam acquires a speed of 62.0m/s
a)what is the magnitude of the force?
b)what is pams final kinetic energy
Homework Equations
a)F=mg
b)Ek=1/2mv^2
The Attempt at a Solution
a)
m=40.0kg
d=22.0m
v=62.0m/s
F=mg
F=(40.0)(9.8)
F=392N
b)
m=40.0
v=62.0
Ek=?
Ek=1/2mv^2
Ek=1/2(40.0)(62.0^2)
Ek=7.69x10^4J
