Problem 5:
A body is projected from the ground at an angle of 30° with the horizontal at an initial speed of 128 ft/s. Ignoring air friction, determine:
a) in how many seconds it will strike the ground.
b) how high it will go.
c) what its range will be.

Problem 4:A body is projected downward at an angle of 30° with the horizontal from the top of a building 170 m high. Its initial speed is 40 m/s.a) How long will it take before striking the ground?b) At what angle with the horizontal will the body strike?
Repeat problem #1 for the case of the body projected downward at an 4. angle of 42 1. A body is projected upward at an angle of 33 with the horizontal from the top of a building 100m high. Its initial speed is 40m/s. (a) How long will it take before striking the ground? (b) How far from the foot of the building will it strike? (c) What is its vertical speed 1.5s after being fired? (d) What are the...
Problem 1 = A brick is given an initial speed of 5 ft/s up an inclined plane at an angle of 30° from the horizontal. The coefficient of friction is u V3/12. After 0.5 seconds, how far is the brick from its original position? You may take g= 32 ft/s?, sin 30º = 1/2, and cos 30º = V3/2.
