Q1. How much would an 80.0 kg person weight (a) on Mars, where an acceleration of gravity is 3.93 m/s2, and (b) on Earth's Moon, where the acceleration of gravity is 1.63 m/s2?
Q2. A 172 ball is tied to a string. It is pulled to an angle of 3.30 and released to swing as a pendulum. A student with a stopwatch finds that 15 oscillations take 18.5.
Q3. A 220 g air-track glider is attached to a spring. The glider is pushed in 12cm against the spring, and then released. A student with a stopwatch finds that 16 oscillations take 11.5.

A 56.0 resistor is connected in parallel with a 117.0 resistor. This parallel group is connected in series with the 27.0 resistor. The total combination is connected across a 15.0 V battery. What is the current of the 117 resistor? What is the power ..
A bat in a cave emits a sound pulse and receives an echo 0.22 second later. Assuming that the speed of sound is 339 m/s, how far did the sound (the longitudinal wave) travel during this time.
How long will it take you to cover the 99 m length of the walkway if, once you get on the walkway, you immediately turn around and start walking in the opposite direction with a speed of 1.5 m/s relative to the walkway.
What is constant acceleration
A cube of ice is taken from the freezer at -8.0°C and placed in a 97 g aluminium calorimeter filled with 286 g of water at room temperature of 20°C. The final situation is observed to be all water at 19°C. What was the mass of the ice cube.
