Answer to Question #133268 in Physics for Shallecke Booysen

Question

Morty, who is wearing frictionless roller skates on a horizontal surface, is pushed by a
Rick with a constant force of 66 N. Using the Work-Energy theorem, calculate how far
the student must be pushed, starting from rest, so that his final kinetic energy is 550 J?

Answer 1

$W=KE$

$W=Fd=66d$ and $KE=550(J)$

$66d=550\to d=550/66=8.33(m)$
