An average-sized portion of spinach has an energy value of about 85 kJ. How many 12-kg crates could a person lift up to a shelf 2.2 m high on the energy from one portion of spinach?

B, if it was a lower watt she could put it in for her normal time and not burn it

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.

Ithink it is c ,i hope i you
