• Pretend that you have just met somebody who has never jumped
before. What instructions could you provide to get the person to jump up (that is, which way do you apply the force when you
push with your feet)?

force is mass*acceleration.

we have a very small mass: 11.4*0.001 kg

if we want 0.035n of force, we need an acceleration:

0.035 = 11.4*0.001*a

a = 0.035/(11.4*0.001) m/s^2

false.

explanation:

this statement is false. after falling for 5 seconds, its speed will not be 100 m/s.
