A 3500 kg car traveling at 65 km/h skids and hits a wall3 s later.The coefficient of friction between the tires and theroad is 0.60. a. What is the speed of the car when it hits thewall? b. What energy must the bumper absorb in order to preventdamageto the car? Assume that the bumper hits the wall

Step 1
The initial speed of the car is given as 65 km/h. To use this value in calculations, we need to convert it to meters per second (m/s). \[ \text{Initial speed (m/s)} = \frac{65 \text{ km/h}}{3.6} = 18.06 \text{ m/s} \] Show more…

A 2000-kg car skidded for a total distance of 18 m (about 60 feet) before coming to a stop. Assuming that the coefficient of kinetic friction between the tires and the road is 0.500, how fast was the car going when the driver slammed on the brakes (thereby locking the wheels)? A. 4.7 m/s B. 7.5 m/s C. 9.8 m/s D. 13.3 m/s E. 17.7 m/s

2000-kg car moving at an initial speed of 25 m/s along a horizontal road skids to a stop in 60 m. (a) Find the energy dissipated by friction. (b) Find the coefficient of kinetic friction between the tires and the road. (Note: When stopping without skidding and using conventional brakes, 100 percent of the kinetic energy is dissipated by friction within the brakes.)
