How much work is done by the force?
W= F * Δs * CosθW= (152N) * (13m) * Cos(33°)
W=1976 * Cos(33°)
W=1657.2
So I'm fairly confident I got this right since the answer is 1660J my question is Why would I have to round it up to 1660 to get it to Joules? I'm not really looking for help on the...
The worker pushes downward and to the left on the box at an angle of 35°. The box has a mass of 135 kg. The box moves horizontally across the floor to the left at a constant velocity. The force applied by the worker is 2030 N∠215°. What is the value of the friction force?Fgravity · sin35° =...
