Atire is rolling along a road, without slipping, with a velocity v. a piece of tape is attached to the tire. when the tape is opposite the road (at the top of the tire), its velocity with respect to the road is: a) 2v. b) zero. c) 1.5v. d) v. e) the velocity depends on the radius of the tire.

2V.

Explanation:

We know rolling motion is superposition of rotational and translational motion.

Also, it is rolling without slipping.

Therefore,       .....1

Where, V is linear velocity and is angular velocity of tire.

Now, at the top point :

Its, linear velocity is V because the tire it is moving with a velocity V.

Now , it is at a distance R from the center of tire.

Its , Velocity due to rotation .  {because is is not slipping}.

Both these velocities are in same direction.

Therefore,

Because,         ( from 1)

Hence, it is the required solution.

dec 23, 2016 - a load of bricks weighing 680 n a distance of 10 m across a parking lot. if if the worker pushes the cart with a constant force of 209 n, what work= force x distance = 220 n x 10 m = 2200 n.m = 2200 j i don't know where the person got it from, but the initial part, work= force x distance me.
