Zookeepers carry a stretcher that holds a sleeping lion. The total mass of the stretcher and lion is 175 kg. The lion's forward acceleration is 2 m/s². What is the force necessary to produce this acceleration?

Answer:

350 N [Forward]

Step-by-step explanation:

Recall the equation for force

Force (N) = mass (kg) * acceleration (m/s²)

or

F = ma

You're given the mass of the stretcher and lion combined is 175kg. Because the lion is in the stretcher, we treat can treat them as one body.

m = 175 kg

You also know the stretcher and lion body is accelerating at 2 m/s².

You have all the information needed to solve.

F = ma

= (175 kg)(2 m/s²)

= 350 N

Because Force is a vector quantity, you have to say the direction. The direction is simply "forward" so make sure to write forward to complete your answer like:

350 N [Forward]
