Question: A projectile is given a velocity v˳ at an angle φ above the horizontal. Determine the distance d

to where it strikes the sloped ground. The acceleration due to gravity is g.

Question: The 400 kg mine car is hoisted up the incline using the cable and motor M. For a short time, the

force in the cable is F=3200 𝑡2 (N) where t is in second. If the car has initial velocity 𝑣1 = 2 m/s at s=0 and

t=0, determine the distance it moves up the plane when t=2 (s).
