Question

A child slides down a hill on a toboggan with an acceleration of 1.5 m/s2.

Part A If she starts at rest, how far has she traveled in 1.0 s? Express your answer using two significant figures. dd = nothing m

Part B If she starts at rest, how far has she traveled in 2.0 s? Express your answer using two significant figures. dd = nothing m

Part C If she starts at rest, how far has she traveled in 3.0 s? Express your answer using two significant figures. dd = nothing m
