Question

A 10-kg wagon is pulled by a force of 70 Newtons while friction provides 20 Newtons of force. How much acceleration will the wagon have?

Answer 1

5m/s²

Step-by-step explanation:

Given parameters:

Mass of wagon = 10kg

Force of pull = 70N

Frictional force = 20N

Unknown:

Acceleration of the wagon = ?

Solution:

Frictional force is a force that opposes motion.

The net force is given as:

Net force = mass x acceleration

Force of pull - Frictional force = mass x acceleration

Insert the parameters and solve;

70 - 20 = 10 x acceleration

50 = 10 x acceleration

Acceleration = 5m/s²
