1.)A force is acting on a 28-kg boy, which accelerates him at 3 m/s². What is the magnitude of the force? 84 N

Formula:

f (?) = ma

m (?) = f/a

a (?) = f/m

Given:

28 kg

3 m/s

Reqn:Force

Eqn/Formula:f = ma

Solution: 28 × 3

84N

h=1/2gt^2

v^2=2gh

v=gt

Explanation:

This problem is an example of uniformly accelerated motion. Horizontal and vertical motions are independent of each other.
