To find the average speed, we must calculate the total distance covered by the object and then divide it by the total time of the motion.
The total distance covered by the object is
while the total time of the motion is
Therefore, the average speed of the object is
It will take the stream 35 minutes to fill 14,700 cubic meters of water
I think the correct answer is a.) it vibrates:]
Answer:
v=5.86 m/s
Explanation:
Given that,
Length of the string, l = 0.8 m
Maximum tension tolerated by the string, F = 15 N
Mass of the ball, m = 0.35 kg
We need to find the maximum speed the ball can have at the top of the circle. The ball is moving under the action of the centripetal force. The length of the string will be the radius of the circular path. The centripetal force is given by the relation as follows :
v is the maximum speed
Hence, the maximum speed of the ball is 5.86 m/s.
