What force is needed to accelerate a child on a sled (total mass=60.0kg) at 1.50m/s^2?

90 N

Explanation:

Force, F is equivalent to the product of mass and acceleration, expressed as Force= ma from Newton's law of motion

Where m is the mass of the object and a is acceleration.

Substituting the total mass of 60 Kg for m and acceleration as given 1.50m/s^2 then the force required will be 60*1.5= 90 N

Therefore, you need force of 90 N
