TOPIC: KINEMATICS
1. A bullet is fired at an initial velocity of 140 m/s and an angle of 60° at the top of a 110 m tall building.
Neglecting air resistance, determine the following:
(a)The maximum height above the level ground that can be reached by the bullet.
(b)The time for the bullet to hit the ground
(cC)The velocity with which the bullet will hit the ground.
B. Show your complete solutions and round off your final answer to 2 decimal places
and box your final answers using a red pen. Make sure your solutions are clearly
written and properly organized.
1. A ball moves in a straight line (the x-axis). The graph in the figure below shows this
ball's velocity as a function of time.

(a) What are the ball's average speed and average velocity during the first 3.0 s?
(b) Suppose that the ball moved in such a way that the graph segment after 2.0 s
was -3.0 m/s instead of +3.0 m/s. Find the ball's average speed and average velocity in
this case.
2. An antelope moving with constant acceleration covers the distance between two
points 70.0 m apart in 6.00 s. Its speed as it passes the second point is 15.0 m/s. (a)
What is its speed at the first point? (b) What is its acceleration?
3. A juggler throws a bowling pin straight up with an initial speed of 8.20 m/s.How
much time elapses until the bowling pin returns…
