A70 kg man goes down a slide inclined 38 degree above horizontal. there is friction and drag.
a) draw the fbd of the man with a coordinate system. write out newton 2nd law for the man.
b) what is the normal force on the man
2. an 87 kg skydiver can be represented as a rectangular "box" with dimensions 22 cm ×37 cm ×1.8m . there is drag.
a) draw the fbd for the skydiver with a coordinate system. write out newton's 2nd law for the skydiver.
b)what is his terminal speed if he falls feet first?
3) figure2 show a 2.0 kg ball os held by two ropes(not moving ).
a) draw the fbd for the ball with a coordinate system. write out newton's 2nd law for the ball .
b) what are the tension in the two ropes?
