formulas givin are s = vavgt, vavg = at, s = vit+ 1/2at, s=1/2 (vf+ vi)t vf = vi + at, 2as =vf-vi
a ball starts from rest and rolls down the incline 4.0ft long,getting to the bottom of the incline after 2.0 s. It the rolls on ahorizontal surface gradually slowing down and coming to rest afterrolling a horizontal distance of 12.0 ft.
a) Velocity of the ball at the bottom of the incline
b) Acceleration of the ball on the incline.
c) Time it took to come to a stop on the horizontal surface.
d) Acceleration of the ball on the horizontal surface.
please show work in simplist form thank you.
