F = m A
(F - 150) = (500 x 7)
F = 150 + (500 x 7) = 150 + 3,500
= 3,650 N
Yes, an object can accelerate without friction. The only thing that is needed to accelerate an object is net force acting on it should not be zero. Then the accleration of body is given by Newton's 2nd Law: F = m*a . For example Rockets in space experience no friction, but they accelerate due to force on them by the exhaust gases.
Force = Mass* Acceleration = 66 Kg * 2 m/second = 132 Kg meters per second per second = 132 Newtons.
By my understanding, this is due to the fact that it is easier to keep a moving object in motion than it is to accelerate it from a resting position. When a force is exerted on a stationary object, acceleration relies on that force alone. However, with a moving body, the momentum of the object reduces the force needed to overcome friction.
F = ma(Force = Mass * Acceleration)F = (3) * (5)F = 15 N(15 Newtons)
90 n is needed to accelerate your body at a rate of 2 if you weigh 45 kg.

It depends on the amount of friction. Higher friction means a higher resistance between the track and coaster which means it is slower. The weight of the coaster does not matter at all. F=ma a=9.8 m/s/s As mass increases, the force needed to accelerate at 9.8 metres per second squared is increased.
F = (M) x (A) = (160) x (2) = 320 newtons.
A car accelerates when the engine produces more power than what is needed to overcome friction. The car reaches its maximum speed (on the level) when all the engine power is being used to overcome friction.
F = (mass) x (acceleration) = (55) x (15) = 825 newtons.
F = ma = 3kg x 9m/s2 = 27N

F = m A = (3 kg) (4 m/s2) = 12 kg-m/s2 = 12 newtons
