PHYSICS 11 / 20 WCLN.ca 5. A projectile is shot straight up leaving the ground at 30 m/s. If air resistance is ignored: a. What is the maximum height it will go? Solve using energy. b. Same question as a), but this time solve using kinematics equations. c. What will be the speed of the object when it reaches a height of 15 m? Solve using energy. d. If the projectile in the previous example has a mass of 2,0 kg and reached the height of 15 m, but only had velocity of 22.2 m/s, how much energy was dissipated as heat due to air resistance
