Question
our Name Date 0. In both of the situations shown at the right, an applied force of 100 N accelerates the 100 N block on top of the table. In which case is the acceleration slowest? 100 100 N a. The one-block system on the right side. b. The two-block system on the left side. c. Both systems have the same acceleration. d. Neither system has a slower acceleration. 100N 100N I 1 . ? If the box being lifted in the picture on the right weighs about 600 N, approximately how much force does the motor at the top need to apply to lift it from the bottom to the top? (Assume no friction for now.) r 10 m 10m =15.5 X 10" N F h (600 N) (10m) F d (600 N) (30m) 30m 1800 N d(600 N) 30m-200 N 12.Of course, there is really is friction. When the box in the previous problem is allowed to slide down from the top of the ramp, it only gets about ? of the way down before it stops. About how much work does friction do to stop the box? a. -2000 10 m c. 4000 J hich of the following illustrations represents the centripetal force vectors acting b. 2000 J d. 6000 J on the cars of a Ferris wheel? b. ?. I d.Explanation / Answer
10] option b is correct.
Two block system will cause less acceleration because in 1 block system Tension is 100N, but it will be lesser in 2 block.
11] option d is correct.
Fmotor = Fg *sin theta = Fg*h/d = 600*10/30 = 200N
12] W= Fx = 200*30*2/3 = 4000 J
option c
13] option b
