I need help with this problem.
A. 3 seconds
B. 1G: 3s, 2G: 3 s, 3G: 4 s, 4G: 8 s, 5G: 42s
C. I used the equation a=changevelocity/changetime sooo 60 mph-0mph/.025 hr = 2400 mph^2 (I'm not sure if that's the way I should have done that for conversions or if I messed up there because it goes wonky from here for me).
D. I looked at the graph and got about 123 mph at 11 seconds. Should I do that a different way?
E. So I found acceleration of all the gears, but this is where I think maybe I messed up with C. Because G1: 2500, G2: 1200, G3: 909.09 G4: 567.16 and G5: 125.7
Then I used the equation X=Vi(t)+1/2a(t)^2 and I did that X1,X2.....X5 and added those values and came up with like 78.35 miles, which cannot be right because we are talking about 60 seconds so I feel like I buggered up with my time or something.
