the end of a cord of length 0.40 m. If the tension in the

cord is 0.80 N when the body is at its highest point,

find:

b the acceleration and the speed of the mass at the

lowest point

c the tension in the cord at the lowest point.

How would you find the velocity for part b?

Would you use mv^2/r=F-mg if not what do i use?

for part c what do i use to find the tension at the lowest point?Do i use the same formula as well for b?
