How fast is the car traveling if it has driven a total of 200 miles in 5.5 hours?
Rom4ik [11]

Average speed = (distance covered) / (time to cover the distance)

                           =  (200 miles)  /  (5.5 hours)

                           =      (200/5.5)  mile/hour

                           =          36.4 miles per hour    (rounded)

A 1500-kg car locks its brakes and skids to a stop on a slippery horizontal road, leaving skid marks that are 15 m long. How muc
Harman [31]

Answer:

E=88200\ J

Explanation:

Given:

  • mass of car, m=1500\ kg
  • distance of skidding after the application of brakes, d=15\ m
  • coefficient of kinetic friction, \mu_k=0.4

<u>So, the energy dissipated during the skidding of car:</u>

<em>Frictional force:</em>

f=\mu_k.N

where N = normal reaction by ground on the car

f=0.4\ties 1500\times 9.8

f=5880\ N

<em>Now from the work-energy equivalence:</em>

E=f.d

E=5880\times 15

E=88200\ J is the dissipated energy.
