First, we will get the distance traveled before the driver applied the brakes. distance = velocity * time distance = 25*0.34 = 8.5 m
Now, we will calculated the distance that the car traveled after the driver applied the brakes. To do this, we will use the equation of motion: <span>vf^2 = vi^2 + 2*a*d where: </span>vf = zero, vi = 25 m/s and a = -7 m/s^2 Note: The negative sign is only to show deceleration d = <span> 1/2*(625) /(7) = 44.6428 m
The total stopping distance =</span> 8.5 + 44.6428 = 53.1428 m
Fossil fuels are non-renewable resources and create greenhouse gases. While cheaper now to burn fossil fuels, within fifty years we will run out and have to turn to other sources of energy. Hope this helps!!!
