For example, say you bowl a bowling ball. Will the bowling balls speed be fastest the moment you bowl the bowling ball? Or will its fastest speed be a second or two later? Will the bowling ball slow d
Someone is driving down a slope of 8 degrees to the horizontal, they then apply the brakes to remain at a constant speed of 60km/h. The breaks pads of the car weigh 100grams each and there are two on
No, a perpetual motion machine is one that uses no net energy to produce energy. Fusion would indeed tap into a powerful energy source, but it, well, USES it. Each bit of energy that it provides is th
A student of mass 36.9 kg wants to measure the mass of a playground merry-go-round, which consists of a solid metal disk of radius R = 1.50 m that is mounted in a horizontal position on a low-friction
During a trip home, my father challenged me with the question At what speed, in m/s, would someone have to travel for yellow to look green? Since I am only in 9th grade high school physics, not even i

A bullet of mass mB = 0.0127 kg is moving with a speed of 101 m/s when it collides with a rod of mass mR = 7.23 kg and length L = 1.09 m (shown in the figure). The rod is initially at rest, in a verti
Im doing a science fair project on how the different types of salt affect the density of the water.
Im only in middle school so can you explain it easy?Thanks.-step 1: you need to get a container, th
Water ripples are produced by making a cork oscillate up and down at a frequency of 5 Hz. The peaks of the ripples are 0.03 meters apart. What is the speed of the water ripples?-v = f . λ=5 . 0.03=0.1
i would really appreciate it if you only solve even one question. i was absent on the day teacher tought this topic.
