A 76-kg ball is tied to one end of a massless string of length 1.3 m. The other end of the string is tied to a nail in the cente
r of a table. The ball is set into uniform circular motion around the nail, and the tension in the string is 51 N. How long does the ball take to make one complete revolution? Assume friction with the table is negligible.

Answer:
Truck will be at a distance of 720 m
Explanation:
Speed of the truck is given as 90 m/sec
Time for which truck travel t = 10 seconds
We have to find the distance that how much truck travel in 8 sec with speed of 90 m/sec
We know that distance is given by
So distance traveled by truck in 8 sec will be equal to
So truck will be at a distance of 720 m
