A sky diver jumps from a high building. He should not release his parachute until his speed is 30 m/s. When falling the air resistance depends on the speed and is given by

a (drag) = 0.003 v2

How far does he drop before reaching a speed of 30 m/s?

a) SCSU physics and astronomy student club has a recently established tradition of pumpkin drop, from the top of Wick Science Building to the "moat" below street level. Although the "experimental data" has not been made public, there have been rumors of the drop took 2.12 seconds, i.e. falling from rest with negligible air drag. Based on the rumor, how tall is the building from the "moat" to the roof? Ignore air drag or any rotation of pumpkins. Hint: You...

1. A careless painter dropped a brush (with paint!) from a scaffold outside a building he's supposed to paint. You were just recording a selfie video across the street and caught the falling brush in your video. You used your physics skills to figure out the paint brush was falling at 4.0 m/s when it was just passing the top of a window that you estimated at 7.0 m above the ground. How long did it take the brush to...

A) A ball is released from the top of a 67.0 m high building. At the same instant a second ball is shot straight up from the ground with an initial speed of 20.0 m/s , directly below the point where the first ball was dropped. Ignore air drag and calculate the height above the ground where the balls collide. the velocity (magnitude and direction) of each ball just before the collision. B) Three vectors A, B, and C each...

• Cooper is standing on a 45◦ hill. He kicks a rock (m = 1kg) with a force of F = 50N down the hill. His foot is in contact with the rock for 0.1 seconds. How fast will the rock be moving after 5 seconds? How long does it take for the rock to travel 100 meters? Ignore pesky friction and rotation. • When an object is falling, it is said to be at terminal velocity if it is...

Merari feels lucky and tries to drag race a Lamborghini in a Camaro? Merari goes from 65 mph (29 m/s) to 90 mph (40.2 m/s) in 3 seconds before realizing that there is no way he's going to catch it. What was the acceleration of Merari's Camaro during this time? For Henry, the worse part of being on lock down is having to deal with his little sister. While studying for his Physics exam she hits Henry in the head...
