1. You have a cat who has a mass of 10 kg and is
chasing a mouse with an acceleration of 10 m/s2.
If it runs into a wall what force will be exerted by
the cat?

2. You are pushing a box with 20 N of force that has
a mass of 10 kg, solve for acceleration.

3. Your dog is dragging you with a force of 100 N at
an acceleration of 4 m/s, what is your mass?

Answer:

1) F = 100N

2) a = 2 m/s²

3) m = 25 kg

Explanation:

1) F = ma ( F = ?, m = 10 kg, a = 10 m/s² )

  F = 10×10

  F = 100 N

2) F = ma ( F = 20N, m = 10 kg, a = ? )

   20 = 10×a

   10a = 20

   a = 20/10

   a = 2 m/s²

3)F = ma ( F = 100N, m = ?, a = 4 m/s² )

  100 = m×4

  4m = 100

  m = 100/4

  m = 25 kg

Hope that helps! Good luck!
