Calculate the average acceleration of your two slopes for each run of Part (3): Calculate the mean value of g and its uncertainty: Calculate the discrepancy between theoretical and experimental values of g: Results (3 points) Part 1: Mcart, g mhang, g Acceleration, m/s2 Average gravitational acceleration, m/s2 % discrepancy Part […]
A diver of mass 75 kg jumps upward off a diving board and into the water. Question 2 A diver of mass 75 kg jumps upward off a diving board and into the water. The diving board is 2 m above the water. a. When the diver jumps, she has a speed of 2.5 m/s. […]
An object is in free fall. At one instant, it is traveling at 46 m/s. Exactly 3.7 s later, what is its speed? The acceleration of gravity is 9.8 m/s? Answer in units of m/s.
Physics question urgently 1. A car accelerates uniformly from rest and travels a distance of 60m in 6s. Calculate the acceleration of the car. Using a=2s/t^2 I get 3.3ms^2 2. A trolley accelerates down a slope. Two photo cells spaced 0.5m apart measure the velocities to be 20cms-1 and 50cms-1. Calculate the time taken to […]
Motion in 1 dimension: Does a ball rolling on an incline have the same acceleration on the way as it does on the way down?
In this lab, you will investigate the motion of an object that is moving in a plane, but not in a straight line. Create a short video of an object moving in two dimensions. You will need at least 30 frames of the object moving. Convert your video to a format LoggerPro can use. When […]
