dew - Quest Learning & Assess x + re.com/courses/2618320/quizzes/5692545/take One group approached their investigation by dropping a mass so it fell vertically downward. They planned to measure the position of the mass as it descended using a motion detector. They checked whether the motion detector that they were using was sensitive enough to capture the motion during the fall, and they were satisfied. Given that they are measuring the motion (position, velocity, and acceleration) of the mass, the students can...

14. Two masses are connected by a string which passes over a pulley with negligible mass and friction. One mass hangs vertically and one mass slides on a frictionless 30.0 degree incline. The vertically hanging mass is 6.00 kg and the mass on the incline is 4.00 kg. The magnitude of the acceleration of the 4.00 kg mass is 15. Two masses are connected by a string which passes over a pulley with negligible mass and friction. One mass hangs...

Investigation 1 - Connected Particles (Maximum Mark 45) A block mass M kg is resting on the horizontal top of a cube. The coefficient of friction between the block and the cube is u. Two strings are attached to the sides of the block. One string passes over a pulley and is attached to an object of mass m kg which is hanging freely a height h metres above the ground. The other string passes over another pulley on the...
