Question 1 (3points):
Calculate the displacement and velocity at time of 0.500 s for a ball thrown straight up with an initial velocity of 15.0 m/s. Take the point of release to be y0=0
Question 2 (3points):
A projectile is launched at ground level with an initial speed of 50.0 m/s at an angle of 30.00 above the horizontal. It strikes a target above the ground 3.00 seconds later. What are the x and y distances from where the projectile was launched to where it lands?
