An object is thrown straight down with an initial speed of from a bridge. If the atmosphere is completely free of air resistance, how fast will the stone be when it enters the water seconds later?
The gravitational acceleration is
An object is thrown straight upward with an initial speed of If the atmosphere is completely free of air resistance, what is its velocity after seconds has passed?
Define upward as positive direction.
The gravitational acceleration is
A bullet is being fired from a pistol. As the bullet is fired, it initially accelerates uniformly at for seconds. After seconds has passed and the bullet has escaped from the pistol, it constantly decelerates at a rate of due to air resistance. What is the speed of the bullet seconds after the trigger is pulled?
Ignore the effect of gravity.
An object is falling with a speed of If the atmosphere is free of air resistance, how fast will the object be falling seconds later?
The gravitational acceleration is
A car that is initially traveling at accelerates uniformly for seconds at a rate of in a straight line. What is the car's velocity after the seconds?
