When the driver applies the brakes of a light truck traveling 42.5 km/h, it skids 2.9 m before stopping. How far (in meter) will the truck skid if it is traveling 99.3 km/h when the brakes are applied? Write your answer to one decimal place. Hint $T_1 + \sum U_{1-2} = T_2$

Step 1
We know that 1 km/h is equal to 0.2778 m/s. So, the speed of the truck when the brakes are applied is 99.3 km/h * 0.2778 m/s = 27.58 m/s. Show more…

When the driver applies the brakes of a light truck traveling $40 \mathrm{km} / \mathrm{h},$ it skids $3 \mathrm{m}$ before stopping. How far will the truck skid if it is traveling $80 \mathrm{km} / \mathrm{h}$ when the brakes are applied?
A truck is traveling at 35 m/s on a slippery road. the driver slams on the brakes and the truck starts to skid. if the coefficient of kinetic friction between the tires and the road is 0.20, how far will the truck skid before stopping?

- A truck is traveling at 11.1 m/s down a hill when the brakes on all four wheels lock. The hill makes an angle of 15o with respect to the horizontal. The coefficient of kinetic friction between the tires and the road is 0.750. How far does the truck skid before coming to a stop?
