A quick thinking 50 kg physics student uses a bedsheet as a makeshift parachute to escape a burning dormitory. The bedsheet provides 400 newtons of air resistance. At what rate does the student accelerate downward? How fast will she be falling when she hits the ground if she jumps from a height of 16 m?

If a tank filled with water contains a block and the height of the water above point a within the block is 0.8 meter, what is the pressure at point a?

Agroup of students were investigating the force of gravity. they began by dropping a foam ball from a height of 3 meters into a bucket of sand. the ball hit the sand in 0.306 seconds. they dropped additional balls of approximately the same diameter, but of different masses. here is the data they collected. based on this experiment and the collected data, what would their conclusion be?

Which of the following is not a means to accelerating? question 4 options: a)increase speed b)remain still c)decrease speed d)change direction
