Question

22. Frank kicks a soccer ball off the ground and in the air, with an initial velocity of 30 feet per second. Using the formula H(t) = -16t2 + vt + s, what is the maximum height the soccer ball reaches? (4 points)

14.1 feet
13.7 feet
13.2 feet
15.2 feet

Answer 1

After 1st bounce => 80(0.6) = 48 metres

2nd bounce => 80(0.6)(0.6) = 80(0.6)² = 28.8 metres

3rd => 80(0.6)³ = 17.28 metres

so, 8th bounce => 80(0.6)⁸ = 1.3 metres
