Q1. A 5.00 x 10^4 kg space probe is travelling at a speed of 14000 m/s through deep space. Retrorockets are fired along the line of motion to decrease the probe's speed. The retrorockets generate a force of 4.00 x 10^5 N over a distance of 2600 km. What is the final speed of probe?
Q2. Car accelerated as stop light changes. The cars linear motion is 0 to 10 m/s in 10 s and the diameter of a tire is .85 m. what is the final angular velocity of tire on the car? What is the angular acceleration of the tire on the car whereas the car is accelerating? Through how many revolutions did the tire rotate though the car was coming up to speed?
A proton is travelling to the right at. It has a head-on perfectly elastic collision with a carbon atom. The mass of the carbon atom is 12 times the mass of the proton. What are the speeds of each after the collision? What is the direction of the pro..
