Two crates, one with mass 5.4 kg and the other with mass 8.2 kg, connected by a light rope. the coefficient of kinetic friction between each crate and the surface is 0.43.the crates are pulled to the right at a constant velocity of 2.9 cm/s by a horizontal force. determine the ratio of the magnitude of the applied horizontal force to the magnitude of the tension in the rope connecting the blocks. use 9.80 meters per second squared for acceleration due to gravity.

Agroup of students were investigating the force of gravity. they began by dropping a foam ball from a height of 3 meters into a bucket of sand. the ball hit the sand in 0.306 seconds. they dropped additional balls of approximately the same diameter, but of different masses. here is the data they collected. based on this experiment and the collected data, what would their conclusion be?

Acentrifuge in a medical laboratory rotates at an angular speed of 3,700 rev/min. when switched off, it rotates through 54.0 revolutions before coming to rest. find the constant angular acceleration (in rad/s2) of the centrifuge. your response is within 10% of the correct value. this may be due to roundoff error, or you could have a mistake in your calculation. carry out all intermediate results to at least four-digit accuracy to minimize roundoff error. rad/s2
