GENERAL PHYSICS LAB SPRING 2022 MID-TERM EXAM STUDENT NAME ................................................................................................. STUDENT NUMBER ............................................................................................. 1. 2. 9' 5-\"? A metallic sphere has a mass of 0.07 Kg. Calculate its density given that its diameter is 2.54 cm. (3mks) State Newton's second law of motion(1mk) In an experiment to verify newton's second law of motion using the atwood machine, a student obtained the following values; Mass of descending weight. m2 = 212.29 Mass of ascending weight. m1 = 200.29 Acceleration, a = 0.269 m/s"2 Using the values given and the equation g{(m2 -m1) I (m2 + m1)} = a. Calculate the value of acceleration due to gravityg (2mks) a) Calculate the percentage error on the value of gravity obtained in b above.(1mk) b) Explain the difference between elastic collision and inelastic. Give an example of each.(4mks) What do you understand by the term vector. Give an example.(2mks) The diagram below shows a rod of length 10m placed horizontally and supported from one end. Three forces, F1. F2, and F3 are acting on it separately. Calculate the torque due to a) F1 (2mks) b) F2 (2mks) c) F3, if it makes an angle of 30 degrees with the rod. (3mks)
