A pendulum of mass 22 kg is released from rest at some height, as shown by point A in the image below. At the bottom of its are at point B, it is traveling at a speed of 13 m/s. What is the approximate amount of energythat has been lost due to friction and air resistance? (Recall that g = 9.8 m/s2) A. 45 J
B. 218
C. 134J
D. 297 J

Arrange the images in order to show how lake-effect snow occurs.

This is the number of complete movements of a wave per second.

An astronaut in space cannot use a scale or balance to weigh objects because there is no gravity. but she does have devices to measure distance and time accurately. she knows her own mass is 77.4 kg , but she is unsure of the mass of a large gas canister in the airless rocket. when this canister is approaching her at 3.50 m/s , she pushes against it, which slows it down to 1.30 m/s (but does not reverse it) and gives her a speed of 2.60 m/s . what is the mass of the canister?
