question 1)

You launch a projectile horizontally from a building 48.2 m above the ground at another building 33.1 m away from the first building. The projectile strikes the second building 12.4 m above the ground. What was the projectile s launch speed?

question 2)

A car drives around a circular track of diameter 87 m at a constant speed of 47.4 m/s. During the time it takes the car to travel 228 degrees around, what is the magnitude of the car s average acceleration?

Two seconds after being projected from ground level, a projectile is displaced 40 m horizontally and 53 m vertically above its launch point. Its horizontal component of initial velocity is v0x=20 m/s. Its vertical component of initial velocity is v0y=36 m/s. At the instant the projectile reaches maximum height above ground level, the displacement is x=74 m. Answer questions a, b, and c below. Show all work and details. Give explanation for your answer. a) What is the horizontal range...
