A car has a drag coefficient Ca = 0.30, a frontal area of A = 1.9 m² , a mass 1.2 tonnes and a coefficient of rolling resistance, C,, = 0.012. It is travelling up a hill with a slope of 1 in 20 at 110 kph. At what rate is it doing work against gravity (i.e. at what rate is it increasing its gravitational potential energy)? Pg = kW. (A 1:20 grade means that it rises 1 m for every 20 m travelled along the road: sin(0) = 1/20.) Enter answer here
