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?
Homework Answers
Answer #1
Use equations of kinematics and vertical and horizontal
direction separately to find the required time and use the time to
find the launch speed which is horizontal.

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.
