A 30 kg dog is running at 1 m/s and quickly comes to a stop when she sees her bone. What is the work required for her to come to a complete stop?

Write short note on the following ; collision theory, rotation angle and angular velocity, centripetal acceleration, coriolis force, and newton's law of gravitation.

The force acting on a beam was measured under the same operating conditions and a sample of 5 data points was collected. this process was repeated by 3 observers. the pooled standard deviations of these 3 data sets was 1.21. determine the true mean force using all pooled data (with a 95% probability). the result should look like this: true mean = mean +/- margin of error

What properties of a moving object are used in determining the object's energy of motion
