Question

Nikolas, the fire extinguisher, and the skateboard have a combined mass of 50 kg. What force would the fire extinguisher have to produce to propel Nikolas if he wanted to accelerate at a rate of 1.2 m/s2? Round your answer to the nearest whole newton.

Answer 1

Answer:

60N

Explanation:

Given parameters:

Combined mass = 50kg

Acceleration  = 1.2m/s²

Unknown:

Force to propel  = ?

Solution:

From Newton's second law of motion, we know that;

       Force  = mass x acceleration

 So;

         Force  = 50 x 1.2  = 60N
