A bicyclist comes to a skidding stop in 10m. During this process, the force on the bicycle due to the road in 200N and is directly opposed to the motion. The work done by the cycle on the road is

A

`+2000 J`

B

`-200 J`

C

zero

D

`-20000 J`

Text Solution

Verified by Experts

The correct Answer is:
C
(c ) Here, work is done by the frictional force on the cycle and is equal to `-200xx10=-2000 J`. As the road is not moving, hence, work done by the cycle on the road =zero.

In a children\'s park, there is a slide which has a total length of 10 m and a height of 8.0 m figure. Vertical ladder are provided to reach the top. A boy weighting 200 N climbs up the ladder to the top of the slide and slides down to the ground. The averages friction offered by the slide is three tenth of his weight. Find a. the work done by the ladder on the boy as he goes up. b. the work done by the slide on the boy as he comes down. Neglect any work done by forces inside the body of the boy.

A bicycle has pedal rods of length 16 cm connected to sprocketed disc of radius 10 cm . The bicycle wheels are 70 cm in diameter and the chain runs over a gear of radius 4cm . The speed of the cycle is constant and the cyclist applies 100 N for, that is always perpendicular to the pedal rod, as shown in figure. Assume tension in the lower part of chain is negligible. The cyclist is peddling at a constant rate of two revolutions per second. Assume that the force applied by other foot is zero when one foot is exerting 100 N force. Neglect friction within cycle parts and the rolling friction. The net force of the friction on the rear wheel due to the road is:

A : When a man is walking on a rough road, that work done by frictiona force is zero. R : Frictional force acts in the direction of the motion of the man in this case.
