A projectile is shot horizontally from the edge of a cliff, 230m above the ground. The projectile lands 300m from the base of the cliff. a. Determine the time taken by the projectile to hit the ground.

b. What is the initial horizontal velocity of the projectile?

c. What is the initial vertical velocity of the projectile?

d. Find the horizontal component of the velocity just before the projectile hits the ground.

e. Find the vertical component of the velocity just before the projectile hits the ground.

f. What is the magnitude and direction of the velocity?

Stealthily, eerily, nervously, fearfully, excitedly, sheepishly, immediately

They way i figured it, i got the answer of a. $120,200

The answer is    (d) 7/2======we have    we also  have an integral      notice how function f splits up at x = 0. there's a left piece and a right pieceso we'll need to do the same thing with our integral: split it at x = 0we use a property of integrals that allows us to split up and sum:     notice that for the piecewise function f, the function has the equationf(x) = x when x  ≤ 0. so for the integral  , f(x) = x so it changes into      for the piecewise function f, the function has the equationf(x) = x+1  when x  > 0. for the integral  , we have    therefore, back to our splitted integral:    

False is the answer    hope to soon
