Two soccer players kick the same 1-kg ball at the same time in opposite directions. one kicks with a force of 25n the other kicks with a force of 10n . what is the resulting acceleration of the ball in m/s^2

Three point charges, two positive and one negative, each having a magnitude of 20 μc are placed at the vertices of an equilateral triangle (30 cm on a side). what is the magnitude of the electrostatic force on the negative charge

If the speed of a particle triples ,by what factor does its kinetic energy increase?

In all trials, the magnitude of the final velocity for g1 + g2 was less than the magnitude of any initial velocity. as mass increased, what happened to the velocity? the velocity decreased. the velocity increased. the velocity of g1 + g2 could not be measured. the velocity was not affected by the mass increase.
