Question
A projectile hits the ground at an angle of 30 degrees below the horizontal with an energy of 113715 Joules. The mass of the projectle is 0.7kg. Assuming that this
projectile was launched from the ground some distance away, determine thet horizontal and vertical velocity components at the launch.
Let the acceleration due to gravity be 9.81ms-2
NOTE: sometimes rounding errors can produce slightly different answers, choose the nearest set of values if your answers don't match exactly.
O Horizontal Velocity = 496.3 m/s and Veritcal Velocity = 285.0 m/s
O Horizontal Velocity = 495.0 m/s and Veritcal Velocity = 283.6 m/s
Horizontal Velocity = 493.6 m/s and Veritcal Velocity = 285.0 m/s
Horizontal Velocity = 493.6 m/s and Veritcal Velocity = 280.5 m/s
