Reaction progress
O A. The height of the curve at point A represents the activation energy
B. The potential energy of the products is greater than the potential
energy of the reactants,
C. The potential energy of the reactants is greater than the potential
energy of the products,
OD. The height of the curve at point Brepresents the activation energy

Answer: it will take   4.36 seconds to reach her average velocity 10.69 miles/hour.explanation:   we have equation of motion ,where s is the displacement, a is the acceleration, u is the initial velocity and t is the time taken.average velocity = displacement/ time taken.average velocity = 10.69 miles/hr = 10.69*1.6*1000/(60*60) = 4.75 m/s4.75 = s/ts = 4. 1we also have acceleration = 2.18 m/s², initial velocity = 0 m/sso it will take   4.36 seconds to reach her average velocity 10.69 miles/hour.
