Homework Statement
A car of mass 1200 kg produces a maximum power of 50 kW. Find the maximum acceleration of the car when it is traveling at 60 mph.
(A). 1.6 m/s2. (B). 0.4 m/s2. (C). 0.7 m/s2. (D). 2 m/s2. (E). 3 m/s2
Homework Equations
P=Fv
F=ma
mph-m/s = (miles x 1.6 x 1000)/3600
The Attempt at a Solution
P=Fv
P=mav
P/mv=a
m/s= (60 x 1.6 x 1000)/ 3600
50000/1200x26.6 = 1.56...
So I'm saying that the anser is 1.6
i think i have done this right however as i no longer have access to the answers i can't tell. If any thing is wrong could you just point me to the area (i.e. equations or numbers)
