M1 is a spherical mass (43.0 kg) at the origin. M2 is also a spherical mass (17.2 kg) and is located on the x-axis at x = 99.0 m. At what value of x would a 16.5-kg mass experience no net gravitational force due to M1 and M2?
For no apparent reason, a poodle is running at a constant speed of 6.00 m/s in a circle with radius 2.9 m. Let v1 be the velocity vector at time t1 , and let V2 be the velocity vector at time t2 . Consider (change in v)=v2-v1 and (change in t)=t2-..
