Question

A ball is thrown from the roof of a building. The initial velocity vector is at an angle of 53.0° above the horizontal. It is at maximum height in 1.04 seconds. Express all vectors in terms of unit vectors i and j. The ball strikes the ground at a horizontal distance from the building of 33.1 meters.

a.) What is the vertical velocity (vector) at t=1.04 seconds?

b.) What is the initial vertical velocity (vector)?

c) What is the inital speed?

d.) What is the initial horizontal velocity (vector)?

e.) What is maximum height of the ball measured from the roof of the building?

f.) What is the horizontal velocity the instant before impact with the ground?

g.) What is the acceleration of the projectile?
