A projectile is launched with an initial speed of 70 m/s at an angle of 35° above the horizontal on flat ground. Neglect air friction.
A)What is the projectile's velocity at the highest point of its trajectory?
A professional golfer launches a ball at an angle of 18.2° above the horizontal axis with an initial speed of 55.8 m/s. What is the maximum height of the ball if we assume no air resistance?
