A 0.25 Kg hockey puck is hit with a force of 7.00 N. The force of friction acting on the puck when it is hit is 0.30 N. What is the magnitude of the acceleration of the hockey puck?
A 12.7 m/s2
B 28.0 m/s2
C 26.8 m/s2
D 29.2 m/s2

Best ResponseYou've already chosen the best response.0C is the answer. just find the net force by subtracting 70.3 and dividing by acceleration

Best ResponseYou've already chosen the best response.0what would the acceleration be in this case? would be have to solve for it?

Best ResponseYou've already chosen the best response.0\[F _{1}F _{2}=ma\] you solve for a by dividing by the mass. F1 is 7 and F2 is .3

Best ResponseYou've already chosen the best response.0force  friction = mass x acceleration 7.0N  0.3N= 0.25 x a 6.7/0.25 = a a=26.8m/s2

Best ResponseYou've already chosen the best response.0This is simply an instantaneous acceleration for the puck at this given moment in time.

Best ResponseYou've already chosen the best response.0F=ma magnitude of the acceleration just means that the acceleration is in the direction of the applied force and it cannot be zero (0). so just keep in mind that magnitude is the same as the size.
