d = 0.5a*t^2 = 10 m.
0.5a*3.9^2 = 10.
0.5a = 0.657.
a = 1.31 m/s^2.
L = 0.5*a*t^2.
a = 1.31 m/s^2.
t = 3.9 + 1 = 4.9 s.
L = ?
A soccer ball is released from the top of a smooth incline. After 3.90 s the ball travels 10.0 m. One second later it has reached the bottom of the incline. Assume the ball's acceleration is constant and determine its value ( m/s2).
How long is the incline?
