Electron Volt

What is the speed of a 300-eV proton? What is the speed of a 300-eV electron? Key: 2.40x10^5, 1.03x10^7

Catching a speeder

An unmarked police car traveling a constant 115 km/h is passed by a speeder traveling 140 km/h. Precisely 1.00 s after the speeder passes, the policeman steps on the accelerator. If the police car's acceleration is 3.00 m/s2, how much time passes after the speeder passes before the police car overtakes the speeder (assumed movin ...continues

Kinematics in one dimension

An automobile traveling v = 85 km/h overtakes a L = 1.15 km long train traveling in the same direction on a track parallel to the road. If the train's speed is 80 km/h, how long does it take the car to pass it (min), and how far will the car have traveled in this time? (km) What are the results if the car and train are travel ...continues

Kinematics in one dimension

A car traveling at 95 km/h strikes a tree. The front end of the car compresses and the driver comes to rest after traveling 0.77 m. What was the average acceleration of the driver during the collision? Express the answer in terms of "g's," where 1.00g = 9.80 m/s2.

Kinematics in one dimension

Two locomotives approach each other on parallel tracks. Each has a speed of v = 80 km/h with respect to the ground. If they are initially d = 9.0 km apart, how long will it be before they reach each other?
