A baseball player is stealing second base when he goes into a slide, which gives him an acceleration of - 2.5 m/s2. If he had an initial speed of 7 m/s, how far does he slide before coming to a complete stop?

First, find Δt

Δt = velocity:acceleration

⇔ (0-7) : (-2.5)

⇔2.8 seconds.

replace it in ΔX=1/2aΔt^2+viΔt

⇔ ΔX = 1/2 (-2.5) (2.8) ^2+7 (2.8)

⇔9.8m
