1.	A motor cycle and rider having a total weightW=1500N travels in a vertical plane following acurve of radius r=50m at a speed of 10m/sec.Compute the thrust exerted by the road as itpasses over the crest C on the curve as shownin the Fig. Assume g=10m/s2ans.1600N1500N1000N1200N
Answer» In cases like these, the thrust (or normal) exerted by the road is the SUM or difference of the weight of the body and centripetal force. In this case,. thrust = weight - centripetal force = mg - m v^2 / R = 1500 - (1500/10) × ( 10^2 ) / 50 = 1500 - 150 × 100 / 50 = 1500 - 300 = 1200 N PS- The figure is not given and the question isn't as clear, but this is what I think the question is asking. Do TELL me if I'm wrong.

Answer»

In cases like these, the thrust (or normal) exerted by the road is the SUM or difference of the weight of the body and centripetal force.

In this case,. thrust = weight - centripetal force

= mg - m v^2 / R

= 1500 - (1500/10) × ( 10^2 ) / 50

= 1500 - 150 × 100 / 50

= 1500 - 300

= 1200 N

PS- The figure is not given and the question isn't as clear, but this is what I think the question is asking. Do TELL me if I'm wrong.
