A 1200 kg car is coasting at 18 m/s. The coefficient of friction between tires and road is 0.62. Find the force of kinetic friction acting on the car.

f=gm1m2/d^2 it d

f is force g is gravitaiton constant, m1 is mass of first object, m2 is mass of second object. d is distance between two object

potential energy is directly proportional to height.

more height = more potential energy.

greatest increase in height = greatest increase in potential energy

where are the points with the greatest increase in height ?

has to be c-e or d-e .

think its the third option

kepler used the data from tycho blahe (his mentor) to construct the laws of planetary motion.
