Answer:
90 m/s
Explanation:
The formula for velocity of wave in a string is given as,
v' = √(T/m') ................ Equation 1
Where v' = velocity of the string, T = Tension on the string, m' = mass per unit length of the string.
Given: T = 4050 N, and
m' = m/l where m = mass of the string, l = length of the spring.
m = 0.5 kg, l = 1 m
m' = 0.5/1 = 0.5 kg/m
Substitute into equation 1
v' = √(4050/0.5)
v' = √(8100)
v' = 90 m/s.
Hence the velocity of the wave in the string = 90 m/s
