1. An object moves on a horizontal circular trajectory of
radius 20m. Find the net force acting on the object after 5s of
motion. Consider that the object starts from rest, moves with a
constant angular acceleration of 5rad/s2 and has the mass of
50kg.
2. A projectile is launched at an angle θ = 30° from the
horizontal from a height of 4ft. At what height will be the
projectile when reaches x = 20ft from the launching point in the
horizontal direction? Neglect the air resistance and consider an
initial velocity of 25ft/s.
