At a certain moment, a car travelling at 40mph begins braking for a railroad crossing. Assume thatthe acceleration is constant (
egoroff_w [7]

Answer:

Part a)

v_f = 17.88 - (0.15) t

Part b)

d = 1072.8 m

Explanation:

As we know that initial speed of the car is

v = 40 mph

v = 40 \times (\frac{1609}{3600})

v = 17.88 m/s

now we have

v_f = v_i + at

0 = 17.88 + a(120)

a = -0.15 m/s^2

Part a)

As we know that acceleration is constant here

so we have

v_f = v_i + at

v_f = 17.88 - (0.15) t

Part b)

distance moved by the car is given as

d = \frac{v_F + v_i}{2} t

now we have

d = \frac{0 + 17.88}{2}(120)

d = 1072.8 m
