And object with a mass of 200kg is sitting on and ice rink (no resistance) what will be its acceleration if the following forces are applied? F1: 80N[N 50 E] F2: 70N[S60 W] F3: 40N[West]

What is the average speed of a car that travels 40mph for 1 hour and 60 mph in another hour will mark brainliest

Atelevision set that has been running for a while heats up even the air around it. which two laws of thermodynamics could be used to analyze this scenario

Arocket starts from rest and moves upward from the surface of the earth. for the first 10.0 s of its motion, the vertical acceleration of the rocket is given by ay = 12.80 m/s32t, where the +y-direction is upward. (a) what is the height of the rocket above the surface of the earth at t = 10.0 s? b) what is the speed of the rocket when it is 325 m above the surface of the earth?
