How can a change be seen in a force on a velocity vs time graph

If a particle undergoes shm with amplitude 0.21 m, what is the total distance it travels in one period?

Before the invention of a wheel turning on an axle, ancient people moved heavy loads by placing rollers under them. (Modern people use rollers, too. Any hardware store will sell you a roller bearing for a lazy susan.

A tennis ball connected to a string is spun around in a vertical, circular path at a uniform speed. The ball has a mass m = 0.16 kg and moves at v = 5.33 m/s. The circular path has a radius of R = 1.13 m.

What is the theory of super symmetry? a. The theory is the same as the conservation of energy. c. It states that for every particle found there is an identical particle that is the same in every way except for mass. b.

A train starts from rest and travels for 5.0 s with a uniform acceleration of 1.5 m/s 2. How far does the train travel in this time interval?

What effect do oceans have on the temperature of coastal areas? A. Ocean breezes warm the coastal land constantly. B. Ocean currents always cool a coastline. C. Ocean winds prevent extremes of temperature on coastal lands. D.

Vf=vi+at solve for t

A solenoid is formed by winding 23.0 m of insulated silver (resistivity 1.59 * 10-8 Ω·m) wire around a hollow cylinder. The turns are wound as closely as possible without overlapping, and the insulating coat on the wire is negligibly thin.

How would you describe the two projectors used to screen a three-dimensional movie? A. Both projectors have vertical polarizers. B. One projector has a vertical polarizer and the other has a horizontal polarizer. C.

A roller coaster has a mass of 500 kg. It drops from rest at the top of a hill that's 57 m tall. How fast is it going when it reaches the bottom? Acceleration due to gravity is g = 9.8 m/s2.
