Final answer:
The kinetic energy of a 35.2 kg toy car depends on its velocity, which is not provided in the question. To find the kinetic energy, we would use the formula KE = 1/2 * m * v^2 with the given mass and known velocity.
Step-by-step explanation:
To determine how much energy a 35.2 kg toy car has when moving at a certain velocity, we need to calculate its kinetic energy. The equation for kinetic energy (KE) is KE = 1/2 * m * v2, where m is the mass of the object and v is its velocity. Unfortunately, the velocity (v) is not provided in the question. If we had the velocity, we could insert the mass (35.2 kg) and the velocity into the formula and solve for the kinetic energy of the toy car.
Without the velocity, we cannot complete the calculation. However, as an example, if the toy car were moving at 10 m/s, the kinetic energy would be calculated as follows:
KE = 1/2 * 35.2 kg * (10 m/s)2 = 1/2 * 35.2 kg * 100 m2/s2 = 1760 J
