A 20-kg child slides down a playground slide with a constant acceleration of a = 1.8 m/s2 parallel to the surface of the slide. The child starts sliding with an initial speed of v0. Refer to the figure. 1.Enter an expression for the child's speed squared, vf2, at the bottom of the slide in terms of a, v0, and the length of the slide, d. 2. If the slide is 4.0 m long and the child's final speed is vf = 5.0 m/s, what is their initial speed, in meters per second? 3. When starting from rest, how long, in seconds, does it take the child to reach the bottom of the slide?
