a)the speed with which the ball was thrown upwards = 6.11 m/s
v^2 - u^2 = 2gH
0 - 6.11^2 = 2*-9.8*H
H = 1.9 m
height to which the ball goes up = 14.9+1.9 = 16.8 m
speed at which the impact = sqrt(2gH) = sqrt(2*9.8*16.8) = 18.14 m/s
b) time taken to reach the top
v = u + gt
0 = 6.11 - 9.8*t
t = 0.623 s
v = u + gt
18.14 = 0 +9.8*t
t = 1.877 s
total time in air = 1.877 + 0.623 = 2.5 s

While standing at the edge of the roof of a building, a man throws a stone upward with an initial speed of 6.95 m/s. The stone subsequently falls to the ground, which is 13.7 m below the point where the stone leaves his hand. At what speed does the stone impact the ground? Ignore air resistance and use ?=9.81 m/s2 for the acceleration due to gravity. impact speed: m/s How much time is the stone in the air? elapsed time:...

While standing at the edge of the roof of a building, you throw a stone upward with an initial speed of 7.39 m/s. The stone subsequently falls to the ground, which is 16.9 m below the point where the stone leaves your hand. At what speed does the stone impact the ground? How much time is the stone in the air? Ignore air resistance and take g -9.81 m/s. (This is NOT a suggestion to carry out such an experiment!)
