Adelivery company has unloaded a 21 kg crate in your driveway. the coefficient of static friction between the crate and the driveway surface is μs = 0.70. the coefficient of kinetic friction is μk = 0.60. in order to move the crate, you apply a horizontal force of magnitude f by pushing on it. as a result, the crate slides with an acceleration of 4.0 m/s2. what is the force f?

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?

Infrared radiation has wavelengths that are shorter than visible light is part of the visible light spectrum has wavelengths that are longer than visible light has the same wavelengths as ultraviolet radiation
