IF YOU GET IT RIGHT, I'LL GIVE YOU THE BRAINLIEST AND NEED EXPLANATION 5. A ball is thrown at 14 ms-1
at an angle of 45o
to the horizontal. Assume the thrower’s arm is 2 m
above the ground when the ball is released.
a. What are the known SUVAT variables for:
i. its horizontal motion
ii. its vertical motion
b. How long does it take for the ball to reach the peak of its trajectory?
c. How high is the ball at this point?
d. What are the vertical and horizontal components of the ball’s velocity after 0.5 s?
e. What is the ball’s velocity (magnitude and direction) after 0.5 s?
6. Imagine the thrower in Q5 is standing on the edge of a 50 m high cliff.
a. Find an algebraic expression for the vertical displacement sV of the ball at time t.
b. Find an algebraic expression for the horizontal displacement sH of the ball at time t.
c. Eliminate t to find an expression for sV in terms of sH.
d. Plot a graph of vertical displacement against horizontal displacement up to sH = 45 m.
e. What is a graph with this shape called?
f. What is the horizontal displacement when the ball lands in the sea?
