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.

The force needed to accelerate a 3kg skateboard at 9 m/s^2 can be calculated using the formula: force = mass x acceleration. Plugging in the values gives: force = 3kg x 9 m/s^2 = 27 N. So, 27 Newtons of force are needed to accelerate the 3kg skateboard at 9 m/s^2.
acceleration...
F = ma(Force = Mass * Acceleration)F = (3) * (5)F = 15 N(15 Newtons)
F = M A = (13) x (25) = 325 newtons
...he exerts against the ground
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.
The force needed to accelerate the box is the sum of the force required to overcome friction and the force required to accelerate the box. Using Newton's second law (F = ma), the total force needed would be: F = (500kg * 7m/s^2) + 150N F = 3850N + 150N F = 4000N Therefore, a force of 4000N is needed to accelerate the 500kg box at 7m/s^2, considering the 150N friction.
A newton is the unit of force in the International System of Units (SI). It is defined as the amount of force needed to accelerate a mass of one kilogram by one meter per second squared.
F = ma = 3kg x 9m/s2 = 27N
