Question

Two ice skaters stand next to each other on a frozen pond. The first skater has a mass of 65 kg and the

second skater has a mass of 82 kg. If the first skater pushes against the second with a force of 35 N, south, what are their respective
accelerations?
help me !!!

Answer 1

D

Step-by-step explanation:

Given that:

Mass of the first skater = 65kg

Mass of the second skater = 82kg

Force of push = 35N

Unknown:

Their respective accelerations = ?

Solution:

To solve this problem;

Force = mass x acceleration

From Newton's third law of motion, we know that action and reaction are equal and opposite.

So, the force on both Skaters is 35N

Acceleration of first Skater =
`(35)/(65)` = 0.54m/s² North

Acceleration of second Skater =
`(35)/(82)` = 0.43m/s² South
