Perform the “Calculating Horsepower” feature earlier in the chapter for a truck that weighs 2,500 kg, travels at a speed of 60 mph, and takes 10 seconds to reach 60 mph.
What will be an ideal response?
(60 mph)(0.447) = 26.82 m/s; W = -½ (2,500 kg)(26.82 m/s) 2 = 899.1 kJ
W = 899.1 kJ/10 s = 89.9 kW
