brenda pushes a box horizontally with a force of 200 N (F=200N). The mass of the box is 50 kg. Assume the friction force is zero. What is the horizontal acceleration of the box?
Four of your PHSE 212 classmates, Henco, Elana, California, and Maloma, were studying for the SU 2 eFundi test when they came across the following
question in the Physics textbook, which stated that: Two identical stones attached to cords are being whirled on a tabletop at the same speed as show
in the drawing below. The radius of the larger circle is twice that of the smaller circle. How is the tension T, in the longer cord related to the tension T2
in the shorter cord? In response to the question, Henco stated that T, = 2T, Elana stated that T = ½ T,, California stated that T, = 4T,, and Maloma
stated that T1= T2.
