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

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

force = mass*acceleration

F = ma

F = 66 kg *  2m/s

F = 132 kgm/s

the moon affects the earth gravitation ally, causing certain motions of that body and also producing tides in its ocean and atmosphere. the tidal wave in our atmosphere is, however, far too minute to be an effective cause in any known meteorological phenomenon.

explanation:

that would be because of both gravity and friction. so     c
