Q1. A 27 pound meteorite struck the car, leaving a dent 24 cm deep in the trunk. If the meteorite struck the car with a speed of 440 m/s, what was the magnitude of its deceleration, assuming it to be constant?
Q2. Assume intelligent life is discovered on a planet orbiting a star 5 light years away from the sun. After many years of communication and planning, an exchange program is arranged thusly:
Interstellar spaceships will be launched simultaneously from each planet toward the other. Both spaceships will travel at v/c=0.60 towards the other planet. To avoid the accidental head on collision, each spaceship will flash an omni directional light beacon at a rate of 10^-6 years (about once every 30 seconds) as measured in the spaceship's IRF. The beacon would be turned on immediately after launch.
Neatly sketch a Minkowski Diagram for this situation. Label all events and axes.
An intergalactic rock star bangs his drum every 1.52 s. A person on earth measures that time between beats is 2.10 s. How fast is the rock star moving relative to the earth.
Find the final displacement from the starting point. How much greater was the distance she walked than her displacement.
Clarify how Einstein's contribution to understanding the force between the earth and the moon differed from Newton's. Include a short statement of Einstein's explanation in the answer.
A capacitor is connected across the terminals of an ac generator that has a frequency of 370 Hz and supplies a voltage of 15 V. When a second capacitor is connected in parallel with the first one, the current from the generator increases by 0.27 A. D..
What is change in the car's kinetic energy KEf - KEo from A to B. How fast will the father be moving.
Monochromatic light from a distant source is incident on a slit 0.750 {rm mm} wide. On a screen 2.00 {rm m} away, the distance from the central maximum of the diffraction pattern to the first least amount is measured to be 1.35 {rm mm}.
A car moves from a point located 26.0 m from the origin and at an angle of 35.0 from the x-axis to the point located 57.0 m from the origin and at an angle of 60.0 from the x-axis in 2.52 s.
A person whose eyes are H = 1.64 m above the floor stands L = 2.3 m in front of a vertical plane mirror whose bottom edge is 38 cm above the floor. What is the horizontal distance x to the base of the wall supporting the mirror of the nearest point o..

Apply those results to get how much slower a clock goes near the earth than one, which is higher up.
Two projectiles are thrown with the same initial speed, one at an angle with respect to the level ground and the other at angle 90 degree. Both projectiles strike the ground at the equivalent distance from the projection point. Are both projectiles i..
