Question

If a 75 kg person on a 15 kg sled is pushed with a force of 900 N, what will teh person's acceleration be?

Answer 1

`10 ms^-2`

Explanation:

Here,
Mass of the person `m_1 = 75kg`
Mass of the sled `m_2 = 15kg`
Total mass `m = m_1+m_2 = 90 kg`
Force applied `F = 900N`

Acceleration(a) = ?
We have,
`F = m xx a`
`-> 900 = 90 xx a`
`-> a = 900/90`
`-> a = 10ms^-2`
Hence, the acceleration of the person is `10 ms^-2`.
