Question

A train moving west with an initial velocity of 20 m/s accelerates at 4 m/s' for 10 secon

moves a distance of
a
meters.

Answer 1

Distance of 400m.

Step-by-step explanation:

Use your kinematics equation to solve for distance (we can use kinematics b/c acceleration is constant).

d = (initial velocity x time) + 1/2 at^2

d = (20 x 10) + 1/2 (4) (10)^2

d = 200 + 200

d = 400 m
