Question

Pam, with a mass of 40.4 kilograms, straps on a rocket pack while wearing her roller blades. The rocket supplies a constant force for 26.7 meters, and Pam acquires a speed of 26.0 meters per second. a. What is Pam's final kinetic energy

Answer 1

Answer:

13.66 kJ

Explanation:

Given that

Mass of Pam, m = 40.4 kg

Distance moved by the force, d = 26.7 m

Speed attained by Pam, v = 26 m/s

The kinetic energy is given by the formula, K.E = 1/2 mv², where

K.E = the needed kinetic energy

m = mass of the object(Pam)

v = velocity of the object(Pam)

Applying the formula, we have

K.E = 1/2 * 40.4 * 26²

K.E = 20.2 * 676

K.E = 13655.2 J

The Kinetic Energy is 13.66 kJ
