Please answer c and d
A rock is thrown upward with a velocity of 10 m/s. Its height ( in meters) after t seconds is given by H= 10t-1.86t2..
c. When will be the rock hit the surface?
d. With what velocity with the rock hit the surface?
Given H= 10t -1.86t2.
Rock will hit the ground when H=0
Plugging H=0 in above equation and solving for t
0 = 10t-1.86t2
0 = t(10-1.86t)
