At the instant the traffic light turns green, an automobile starts with a constant acceleration a of 2.70 m/s2. at the same inst

77julia77 [94]

You know that t=0 and x=0, the car starts moving with a constant acceleration of 2.70m/s²

At the same time, a truck moving speed o 8.50 m/s passes the car

D=v.t (for the truck)

And d= v.t+1/2.a.t²(for the car)

v.t=1/2.a.t²

t=2.v/a

t=2.8.50 m/s/ 2.70 m/s²

17m/2.70=6.29

This mean that the distance is

D=v.t=8.50m/s.6.29= 53.465 m/s

The speed of the car is

Vcar=a.t

2.7m/s2×× 53.65

=144.34
