A brand-new pick-up truck was driven and tested on a national highway. Due to a very light traffic, 8hp is highly required to drive the said vehicle with a mass of 1800kg at a speed rate of 60kph. Consider the friction and air resistance. a) How much power is needed in order to drive the truck at a same rate up a 10% grade (a hill rising 10m vertically in 100m horizontally)? (in hp) b) Meanwhile, how much power is required for the truck still at a same rate down a 1% grade? (in hp)

Question
A brand-new pick-up truck was driven and tested on a national highway. Due to a very
light traffic, 8hp is highly required to drive the said vehicle with a mass of 1800kg at a
speed rate of 60kph. Consider the friction and air resistance.
a) How much power is needed in order to drive the truck at a same rate up a 10%
grade (a hill rising 10m vertically in 100m horizontally)? (in hp)
b) Meanwhile, how much power is required for the truck still at a same rate down a
1% grade? (in hp)
