Well it's an kinematics project and it involves alot of questions. So here goes the problem:

Question

Suppose a football was thrown at an angle of 37 degrees with a velocity of 90mi/hr while leaving a quarterback hand at a height of 6'4" above the ground. A)Calculate the maximum height of the football after being thrown. B)Find the velocity vector at the maximum height. C) find the acceleration vector at the maximum height D) calculate the time traveled before the ball was caught at the height it waas thrown. E)How far did the ball travel before being caught F) calculate the force needed for a 185lb receiver to leap and catch the ball at the height it was thrown hint:the tme it took the receiver to accelerate from the ground was 0.25seconds. G) calculate the impulse experienced when the receiver landed firmly on the ground after catching the ball H) estimate the average force exerted on the person's feet by the ground after landing stiff legged, assume the body moved 1.0cm during impact. After catching the ball and landing onto the field the receiver is immediately tackled by a 150lb strong safety with an initial velocity of 25mi/hr. I) Calculate the final velocity of the two colliding masses J) Calculate how much of the strong safety initial kinetic energy is transformed to thermal or other forms of energy after the collision.
