Force = mass * acceleration
Force = (3 kg)(5 m/s2)
= 15 Newtons

1.5 miles per second2 is 246 G's. In order to accelerate it at that rate, you'd have to push it with a force that's 246 times as much as it weighs, and I'd suggest that you don't do that while anybody is sitting in it.
The force of the hammer is much greater than the force of the nail. Gravity pulls down the hammer, hits the nail, and the nail forces up, but the force of gravity wins over the force pulling on the nail.
Pressure = force / area,so: force = pressure x area You would first have to calculate the area.

F = ma(Force = Mass * Acceleration)F = (3) * (5)F = 15 N(15 Newtons)
acceleration...
F = M A = (13) x (25) = 325 newtons
...he exerts against the ground
Force = Mass* Acceleration = 66 Kg * 2 m/second = 132 Kg meters per second per second = 132 Newtons.
F = (M) x (A) = (160) x (2) = 320 newtons.
F = (mass) x (acceleration) = (55) x (15) = 825 newtons.
There is some confusion here. 500 newtons IS a force. You don't "give a force an acceleration". You can accelerate an object (which has a mass), but not a force.
F = ma = 3kg x 9m/s2 = 27N

Force = mass * acceleration Force = (4kg + 46kg) * 3 m/s2 Force = 50kg * 3 m/s2 Force = 150 kg*m/s2 or Force = 150 Newtons
