Question

How much force would be needed to accelerate a 66 kg skier at 2 m/sec

Answer 1

force = mass*acceleration

F = ma

F = 66 kg * 2m/s

F = 132 kgm/s

Answer 2

Assuming you meant:

How much force would be needed to accelerate a 66 kg skier at 2 m/sec^2:

Force(in Newtons) = mass(in kg) * acceleration(in m/s^2)

F = ma

F = (66)(2)

F = 132N
