A toy car speeds up from rest until reaching a velocity of 9 m/s. The cart has a mass of 8 Kg. What is it final kinetic energy, in Joules? Do not include units in your answer.

Step 1
Step 1: Calculate the final kinetic energy using the formula: \( KE = \frac{1}{2}mv^2 \) where \( m = 8 \, \text{Kg} \) (mass of the car) and \( v = 9 \, \text{m/s} \) (final velocity of the car). Show more…

John's mass is 79.37 kg. He runs and jumps into a cart at rest with a mass of 136.07 kg. The initial speed of John is 8 m/s. What is the final speed of the cart after John jumps in? What is the change in kinetic energy from before to after the collision?

A small cart with an electric motor starts from rest at the top of a peak 4.00 m high, and goes down a track as shown in the figure. The electric motor does 1.81 J of work on the cart as it travels from the top at 4.00 m high, to the next peak, which is 2.00 m high. The mass of the cart is 0.150 kg. At the top of the 2.00 m peak the kinetic energy is 2.60 J. What was the change in thermal energy of the system? Express your answer in Joules to 3 significant figures. Use g=9.81 m/s^2.

REFERRING TO EXAMPLE $9-9$ Suppose that cart 1 has a mass of 3.00 $\mathrm{kg}$ and an initial speed of 0.250 $\mathrm{m} / \mathrm{s} .$ Cart 2 has a mass of 1.00 $\mathrm{kg}$ and is at rest initially.(a) What is the final speed of the carts? (b) How much kinetic energy is lost as a result of the collision?
