Answer:
The tension in the rope is 49.66 N.
Explanation:
Given that,
Mass of bucket m= 23.0 kg
Diameter = 0.300 m
Mass of rope M= 13.0 kg
Height = 10.5 m
Suppose we need to find the tension in the rope while the bucket is falling.
We need to calculate the acceleration
Using balance equation
..(I)
We need to calculate the tension in the rope
Using formula of tension
....(II)
Put the value of T in the equation (I)
Put the value into the formula
Now, put the value of a in equation (II)
Hence, The tension in the rope is 49.66 N.
Answer:
The average force exerted by the person on the box is 20 N.
Explanation:
Given that,
Impulse applied to the box, m = 5 kg-m/s
Time of contact of the person with the box is 0.25 seconds. We need to find the average force exerted by the person on the box. The impulse applied on an object is given by :
F is the average force exerted by the person on the box
F = 20 N
So, the average force exerted by the person on the box is 20 N. Hence, this is the required solution.
The period of the wave would be halved
