Q. A 6.00 x10^4 kg space probe is traveling at a speed of 14000 m/s through deep space. Retrorockets are fired along the line of motion to reduce the probe's speed. The retrorockets generate a force of 5.00 x10^5 N over a distance of 2600 km. What is the final speed of the probe?
Q. Find d, the distance between the photogates, using the times and the glider length. There is two ways to find this for the up and down directions. Meaning if you have 5-7 runs, you should have 20-28 values for d. Using those, find the mean and precision of d. (Be sure to explain what you're doing and use the proper number (20-28) when finding the SDM).
A block of mass 2.7 kg being released from rest on a 1m frictionless plane, inclined at an angle of 40 degree. The block sided down the inclined and struck second block mass of 3.7 kg. If the two blocks stick together, with what speed would they move..

An astronaut on a small planet wishes to measure the local value of g by timing pulses travelling down a wire which has a large object suspended from it. Imagine the wire of mass 3.80 g is 1.60 m long and has a 3.00-kg object suspended from it. A pul..
Rare 1918 "Jenny" stamp, depicting a misprinted, upside-down Curtiss JN-4 "Jenny" airplane, was sold at auction for $525,000. A collector uses a simple magnifiying glass to examine the "Jenny," obtaining a linear magnification of 2.4 when the stam..
A car is driven 125.0 km west and then 65.0 km southwest. What is the displacement of the car from the point of origin (magnitude and direction).

A lead ball is dropped into a lake from a diving board 5 above the water. After entering the water, it sinks to the bottom with the constant velocity equal to the velocity with which it hit the water. The ball reaches the bottom 3.20 after it is f..
A swimmer runs horizontally off a diving board with a speed of 3.58 m/s and hits the water a horizontal distance of 1.79 m from the end of the board. How high above the water was diving board.
A 0.50-kg object is attached to an ideal massless spring of spring constant 20 N/m along a horizontal, frictionless surface. The object oscillates in simple harmonic motion and has a speed of 1.7 m/s at the equilibrium position.
