Question

if wheel revolving at 8rev/sec is brought to rest in 14 sec, then the number of revolution s made by the wheel before coming ro rest.​

Answer 1

Answer:

Firstly we need to find out the total distance.

The wheel takes about 8 revolutions per second.

And it runs for 14 seconds.

Distance = speed x time = 14 x 8 = 112 m.

Now we know the total distance.

The wheel takes 8 revolutions in 1 second, as mentioned above.

Number of revolutions before it comes to rest = 112/8 = 14

Hence it made 14 revolutions before coming to rest.
