100=distance kicked+distance ran
100=48*cos37*t+v*t
but t is time in air.
hf=hi+vi*t -16t^2
0=0+48sin37 t-16t^2
0=t(48sin37-16t)
t=4sin37
so put that t into the distance equation, solve for v.
One wonders why your teacher is not using SI units.
A player kicks a ball at an angle of 37degree with the horizontal and with an initial speed of of 48ft/s. A second player standing at a distance of 100ft from the first in the direction of the kick starts running to meet the ball at the instant it is kicked. How fast must he run in order to catch the ball before it hits the ground? Take g =32ft/sec
