Answer to Question #173092 in Physics for Riad

Question

A air hockey paddle hits a 48.0 g stationary puck with a force of 12.o N. the puck travels 50 cm on the frictionless surface while the force is applied to the puck. Calculate the final speed of the mass at the end of the 50cm

Answer 1

The acceleration, according to Newton's second, is

$$a=F/m.$$

The velocity that the puck will acquire under this acceleration is

$$v=\sqrt{2ad}=\sqrt{2Fd/m}=15.8\text{ m/s}.$$
