You are launching a 2 kg potato out of a potato cannon. the cannon is 1.1 m long and is aimed 65 degrees above the horizontal. it exerts a 48 n force on the potato. what is the kinetic energy (in j) of the potato as it leaves the muzzle of the potato cannon?

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
