What does Newton's first law say that object will tend to do?
If a moving object is losing momentum as time passes, then what does Newton's second law tells us is acting on the object?
____________________ Given that the force is equal to the change in momentum, calculate the force required to bring a marble with a momentum p of 210 g cm/s to a stop in 0.5 seconds.
____________________ When all 67 kilograms of me falls off a RipStik, I accelerate towards the ground at 9.78557 m/s² and then I hit the ground, exerting a force of 1500 Newtons on the ground. Calculate the counter-force that the ground exerts on me.
