$2)$ Have a classmate perform a horizontal jump and use the range and flight time to answer the following questions: range is $2\mathrm{.}84$m flight time is $0\mathrm{.}93$s

a$)$ What is the horizontal velocity?

b$)$ State the equation of height for free$-$falling and calculate the maximum height.

c$)$ Derive the equation of height for free falling using the power rule to obtain a velocity equation.

d$)$ Use the velocity equation to calculate the initial vertical velocity of the jump.

e$)$ What is the angle of take$-$off?
