A -20kg child slides down a playground slide with a constant acceleration of a=2.9 m/s^2 parallel to the surface of the slide. The child starts sliding with an initial speed of v0. Enter an expression for the child's speed squared, vf^2, at the bottom of the skid win terms of a, v0, and the length of the slide, d. If the slide is 4m long and the child's final speed is vf= 5.0m/s, what is their initial speed, in meters per second? When starting from rest, how long, in seconds, does it take the child to reach the bottom of the slide?
