WebNov 2, 2006 · A person holds an 80N weight, 2 meters above the floor for 30 seconds, what is the power required in watts to do this? My answer: 4800watts Wg= -mgd Wg= -80N*2m Wg=-160J Wf=-Wg=160J 1watt=1J/s 30*160J/s=4800J/s=4800watts 10. The speed of a 4.0N hockey puck, sliding on the ice surface decreases at the rate of 0.61m/s^2. WebSep 30, 2024 · Solution: The weight of the block W=mg=300\, {\rm N} W = mg = 300N and the magnitude of the external force are given. (a) Again ''constant speed''. If there is a force equal in magnitude but opposite in direction of the external force, then the net force on the object is zero and, as a result, it moves at a constant speed.

http://mrkeefer.weebly.com/uploads/1/7/0/5/1705042/mechanical_advantage_ws.pdf WebThe normal force will be equal and opposite to the perpendicular gravity component so N = +mg*cos (Θ). To keep the block from sliding, you would then need to apply a horizontal force equal and opposite to the parallel gravity component so that force would be F = +mg*sin (Θ).
