Step 1
The change in kinetic energy (KE) can be calculated using the formula KE = 1/2 mv^2, where m is the mass and v is the velocity. In this case, the initial KE is 0 (since the car starts from rest), and the final KE is 1/2 * 1500 kg * (25 m/s)^2 = 468,750 Joules. So, Show more…

An 860-kg Smart Car has an acceleration of 0.75 ms-2. What is the work done by the net force acting on the car if it travels 45 meters?
Sri K.
A 1500 $\mathrm{kg}$ car begins sliding down a $5.0^{\circ}$ inclined road with a speed of 30 $\mathrm{km} / \mathrm{h}$ . The engine is turned off, and the only forces acting on the car are a net frictional force from the road and the gravitational force. After the car has traveled 50 $\mathrm{m}$ along the road, its speed is 40 $\mathrm{km} / \mathrm{h}$ (a) How much is the mechanical energy of the car reduced because of the net frictional force? (b) What is the magnitude of that net frictional force?
Suppose the 2.0 -kg model car in Exercise 6.41 is initially at rest at $x=0$ and $\vec{F}$ is the net force acting on it. Use the work-energy theorem to find the speed of the car at $(a) x=3.0 \mathrm{m}$ (b) $x=4.0 \mathrm{m} ;(\mathrm{c}) x=7.0 \mathrm{m} .$
