I need help on these physics questions. Can someone please help me with any or all of these. I need to know how to do all of these, so if you guys can take like a question or two and help me with all the question. I need the work and the answer. Thank you so much!
Question #1
An 82.00kg man jumps from the top of a building 37.02m above a net. The air resistance exerts 170.8N force on the man as he falls. What is the velocity of the man just before hitting the net?
Question #2
A .7700kg ball is thrown straight up with initial velocity of 8.720m/s. at the balls peak a .07kg dart, travelling parallel to the ground, with kinetic energy of 73.80J strikes the ball. The dart sticks in the ball after the collision. How far away from the ball’s original position do they land?
Question #3
A cannon fires a 7.120kg projectile at 36.75 degrees. The projectile lands in a cart that is on the same level surface as the cannon. If the 470.6kg cart is pushed 12.35m along the ground in 2.850 seconds Then how fast was the projectile fired?
Question #4
A 5.95kg object is thrown 17.10m/s at a 30 degree angle and collides head on at its peak with a 14.5kg object fired at 27 degrees which Is also at its peak. At what velocity was the 14.5kg object fired?
Question 5
A satellite orbits the earth at 7870m/s. how far from the earth’s surface is the satellite orbiting? At what speed would the satellite have to travel if it’s height above the surface were to be doubled?
Question 6
A 42.75 kg person dives from a 17m platform into a pool. The guy comes to a stop 3.3800m below the surface of the water. What is the change in the guy’s momentum from the top of the platform to the surface of the water? What amount of force is exerted on the guy while being stopped by the water?
Question 7
A .075kg ball is dropped from a height of 18m and bounces vertically until someone finally stops it. The ball loses 17% of its kinetic energy each time it bounces. How high will it bounce the fifth time? What velocity will the ball have right before it hits the ground on that fifth bounce?

Aren't you in school, and didn't you find out how to do these in class? Don't you have a textbook that explains how to do them?

Well Patch : how far have you come so far with answering any of these questions ?
At least show us what you got so far. Surely you do not expect us to do your homework ?
