Answer:
139.6m/s
Explanation:
Calculate the tension first, T=m*g
mass(m): 1750kg, gravity(g): 9.8m/s^2
T= 1750*9.8
=17150N
Then calculate the wave speed using the equation v = √ (T/μ)
v= √(17150N)/(0.88kg/m)
=139.6m/s
143m/s if you just perhaps by what you know you'll figure it out
0.0605J is your answer. Use the formula KE=1/2mv^2
Answer:
I'm pretty sure its the 2nd one.
