A 85.0 kg skateboarder starts from rest at the top of a hill 300. meters in length at an angle of 7.00 degrees. The wheels and the air produce 70.0 N of friction. Find the speed of the skateboarder at the bottom of the hill. a Answer value

Aprojectile is launched horizontally 10m above the ground and with an initial velocity of 15 m/s. a) sketch the trajectory using an appropriate coordination system. b) how long for the projectile to reach the ground. c) how far did projectile travel horizontally before striking the ground. d) determine the projectilex & y position at t-1.3s e) determine the magnitude and direction of projectile velocity at t= 1.3s f) determine the magnitude and direction of projectile acceleration at t-1.3s
