Question: A point charge q1=15.00 µC is held fixed in space. From a horizontal distance of 7.00cm, a small sphere with mass 4.00 × 103 kg and charge q2=+2.00 µC is fired toward the fixed charge with an initial speed of 35.0 m/s. Gravity can be neglected.
Part A: What is the acceleration of the sphere at the instant when its speed is 28.0m/s?
I want help to find the acceleration of the sphere at the instant when its speed is 28.0m/s.

Scientists have recently shown that a sample of cocaine can be traced to its country of origin by measuring the ration of carbon-13 to nitrogen-15 (both naturally occuring, stable nuclides) in the cocaine sample.
Assume a billiard ball is a solid sphere. Its radius is 3 cm and mass is 500 grams. The coefficient of static friction between the ball and the surface is .70. a) Where should you hit the ball so that it experiences pure rolling motion without the..
