Two hockey players strike a puck of mass 0.169 kg with their sticks simultaneously, exerting forces of 1.25 103 N, directed west, and 9.80 102 N, directed 30.0° east of north. Find the instantaneous acceleration of the puck.
A 2.30 N force pushes it to the left, and a 0.800 N force pushes it to the right. (a) Taking right to be positive, what is the net force acting on it? (b) What is its acceleration?
