Motorcyclist heading east through a small town accelerates at a constant 4.0 m/s2 after he leaves the city limits. at time t

Answer:

a = 4.0m/s^2 ; v = 15m/s E; at t = 0; x1 = 5.0m east

at t = 2.0 s ; x2 = ? ; x3 = ? when v2 = 25 m/s

His position is determined by x = 5.0 m + 0.5at^2

a) His position at t = 2.0 s is 5.0 m + 0.5(4)(2^2 ) and it is 5.0 m + 8 m = 13.0 m from the sign post

b) When his velocity is 25 m/s it corresponds to a time of 25/15 = 5/3 s.

His position at t = 5/3 s is X3= 5m + 0.5(4)(5/3)^2 This position is 10.56 m from the sign post.
