Answer:
Mass of fish=6.252 kg
Explanation:
Force F=0 N to 250 N
Length x=15.0 cm=0.15 m
Frequency f=2.60 Hz
To find
Mass of fish m
Solution
First we need to find spring constant
As we know that the time period is given as
Answer:
W = 750 Joules.
Explanation:
Given that,
Force acting on the object, F = 50 N
Distance moved by the object, d = 15 m
To find,
Work done by the object
Solution,
Let W is the work done by the object. It is given by the product of force and distance. Its expression is given by :
Here, (force and distance are in same direction)
W = 750 Joules
So, the work done by the force is 750 Joules.
