Question

If a 60 kg person on a 15 kg sled is pushed with a force of 300 N, what will be person's acceleration?

Answer 1

`"4 m/s"^2`

Explanation:

From Newton’s second Law

`"F = ma"`

`"a" = "F"/"m" = "300 N"/"60 kg + 15 kg" = "300 N"/"75 kg" = "4 m/s"^2`

Note: Sled mass is added because person will accelerate along with it.
