a 50 kg boy on ice skates throws a 5 kg ball to the left. if the ball ends up going 20 m/s, how fast is the boy going?

b) 10 minutes

girls stopped for 10 minutes.

two charges are fixed in place on the x-axis as shown. the charge at x = 0 is negative and has magnitude q = 2 μcoulombs (1 μcoulomb = 10-6 coulombs). the charge at x = d, (d = +12 cm), is positive and has magnitude q = 4 μcoulombs. find a point x = xo along the x-axis at which the electric field is zero.

6/12=1/2
