1. What force is needed to accelerate an object 5m/s2 if the
object has a mass of 10kg?
Force= Mass x Acceleration
Mass: 10kg Acceleration: 5m/s2 = 10x5= 50N
2. Carlos pushes a 3kg box with a force of 9N. The force of
friction on the box is 3N in the opposite direction. What is the acceleration
of the box?
9N- 3N= 6N 3kg x 6N
= 18 m/s2
