Question

4. A dog pulls a sledge of 50kg with a force of 100N against the 60N friction. how much is the acceleration of the sledge?
[ans: 0.8 kg]​

Answer 1

Explanation:

The net force acting on the sledge is given as 100 N - 60 N = 40 N.

We know that, Acceleration = Force / Mass.

That is, a = 40/50 = 0.8 m/s²

Answer 2

Answer:

This is quite simple.

F = ma + friction

100 = 60 * a + 60

100 - 60 = 60*a

40 = 60*a

a = 40 / 60

a = 0.8
