A force is applied to an object at rest with a mass of 100 kg. The same force is applied to an object at rest with a mass of 1 kg. What differences in their motion would you observe? Explain your reasoning.

Because of your expert physics skills, you have been hired as an analyst in a court case involving an automobile accident. The accident involved a 2,402 kg car (car A) which approached a stationary car of mass 1,506 kg (car B).

What if a tornado reach to the speed of light

When does scattering of light occur?

A 2100 kg car starts from rest and accelerates at a rate of 2.6 m/s2 for 4.0 s. Assume that the force acting to accelerate the car is acting in the same direction as its motion. How much work has the car done?

The speed of a nerve impulse in the human body is about 100 m/s. If you accidentally stub you toe in the dark, estimate the time it takes the nerve impulse to travel to your brain. (Assume that you are approximately 1.
