Answer:
The spring constant is 45.94 N/m.
Explanation:
Given that,
Length = 50 cm
Mass = 270 g
Stretching the spring = 24 cm
We need to calculate the spring constant
Using formula of energy
The change in potential energy equal to the change in kinetic energy.
Put the value into the formula
Hence, The spring constant is 45.94 N/m.
To solve this, you’d multiply 55 by 4, because he is travelling 55 miles every hour, for four hours, which means 55 miles every hour. The answer would be 220.
Answer:
Explanation:
As we projected the balloon at speed vo at an angle of 29 degree
so the two component of velocity is given as
now we know that in x direction we have
in y direction we have
now we have
