Two equally charged, 1.00 g spheres are placed with 2.00 cm between their centers. When released, each begins to accelerate at 225 m/s2.
What is the magnitude of the charge on each sphere?
At time t1 = 2.00 s, the acceleration of a particle in counterclockwise circular motion is (1.00 m/s2) i + (6.00 m/s2) j. It moves at constant speed. At time t2 = 4.00 s (3/4 of a revolution later), its acceleration is (6.00 m/s2) i + (-1.00 m/s2)..
Your expression should give 3.0 m/s for and your answer to part A for theta. Express your answer in terms of theta. Sketch a graph of v versus theta for one complete revolution.

A 1.80 MHz sound wave travels through a pregnant woman's abdomen and is reflected from the fetal heart wall of her unborn baby. The heart wall is moving toward sound receiver as the heart beats.
A projectile is launched at some speed at an angle of 74 degrees and travels a range of 262 meters. The launch angle is after that changed, but the projectile is fired at the same speed as the original case and also travels the same range of 272 m..
