What is the drag force on a 1.6 m wide, 1.4 m high car traveling at 11 m/s (≈ 25 mph)? suppose that the density of air is 1.2 kg/m3. what is the drag force on a 1.6 m wide, 1.4 m high car traveling at 33 m/s (≈ 74 mph)? suppose that the density of air is 1.2 kg/m3.

i think the answer is b

gpe = mass x gravity constant x height or… gpe = mgh

where… mass: measured in kilograms (kg)

gravity: gravity constant on earth = 10.00 m/s2

height: measured in meters (m)

gpe: measured in joules (j) or kilojoules (kj)

how do you solve gpe?

gravitational potential energy (gpe) is the energy an object has because of its position above the. ground.

gpe = mass x gravity constant x height or… gpe = mgh.
