A stone thrown horizontally from a height of 5.72 m hits the ground at a distance of 13.50 m. Calculate the initial speed of the stone. Neglect air resistance Calculate the speed of the stone as it hits the ground. Neglect air resistance.
A fisherman is fishing from a bridge and is using a "30.0-N test line." In other words, the line will sustain a maximum force of 30.0 N without breaking. What is the weight of the heaviest fish that can be pulled up vertically.
A 4 kg model rocket is launched, expelling 40.00 g of burned fuel from its exhaust at a speed of 550m/s. What is the velocity of the rocket after fuel has burned? Hint: Ignore the external forces of gravity and air resistance.
