What is the force needed to accelerate a 0.170 kg hockey puck from rest to 65.2 m/s over a period of 0.610 seconds?
Given:
"m=0.170\\:\\rm kg"
"v_i=0\\:\\rm m\/s, \\; v_f=65.2\\:\\rm m\/s"
"t=0.610\\:\\rm s"
The required force
"F=ma=m\\times\\frac{v_f-v_i}{t}\\\\\n=0.170\\times\\frac{65.2-0}{0.610}=18.2\\:\\rm N"
