just the answers

Answer 1

1) when the rider move through the highest po int the force F-394 N choice is (b) 2) the force cau sin g acceleration -F-154 choice is(e) 3) the tension in the cord T-107 choice is (h) m^ - m 4 )acceleration of masses -a- 2g- 4.2m/s2 choice is(b) 5) tension on the cord =T=28.0 N choiceis (f)
