A 50kg child on a skateboard experiences a 75n force, the expected acceleration of the child is 1.5 meters/second squared
Using the formula: F=ma where:
F = Force in Newtons (75n)
m = mass in kilograms (50 kg)
a = acceleration in meters/second squared
F-ma
a = F/m
a = 75 / 50 = 1.5 meters/second squared
