Question

Engineers want to design brakes that will reduce stopping distances by 10%. How would this change the equation relating speed s, friction f, and stopping distance d?
s=30√fd
A)s=√0.09fd=0.3√fd
b)s=0.09√30fd
c)s=0.9√fd
d)s=√27fd=3√3fd

Answer 1

does no one know how to do this? ive seen like 8 people look at it
