Starting from rest, a car accelerates at 2.1 m/s2 up a hill that is inclined 5.1 ∘ above the horizontal. How far horizontally has the car traveled in 14 s ? How far vertically has the car traveled in 14 s ?

Question

Starting from rest, a car accelerates at 2.1 m/s2 up a hill that is inclined 5.1 ∘ above the horizontal. How far horizontally has the car traveled in 14 s ? How far vertically has the car traveled in 14 s ?
Express your answer using two significant figures.

R_scott · Answer

distance up the hill (d) ... 1/2 a t^2 ... 1/2 * 2.1 * 14^2 horizontal ... d * cos(5.1º) vertical ... d * sin(5.1º)
