Jimmy's heart accelerates 2.4 x 102kg of blood from 0.15 m/s to 0.32 m/s over an elapsed time of 0.12s
every time he sees Janine. Find the magnitude of the acceleration of the blood and use that value to
calculate the net force needed to cause that acceleration.
In an elevator problem, how do we know to use only the 2nd Newton law of motion for scale or elevator at rest?
A 4.0 kg object has a velocity of 3i m/s at one instant. Eight seconds later, its velocity is (8i + 10j) m/s. Assuming the object was subject to a constant net force, find (a) the components of the force and (b) its magnitude. show complete solution

- According the 3rd law of motion, you act on the planet Earth with the same amount of force it acts on you with. This is of course the force of gravity. However, if you were to fall down, how come you do not notice the Earth being pulled upward? Suppose everyone in the world jump all at once. Could the jumping move the Earth?arrow_forwardAll the forces we see and experience are the result of just a few so-called fundamental forces. What are the fundamental forces in nature?

(a) Calculate its magnitude of acceleration in a vertical takeoff from the Moon. m/s2 (b) Could it lift off from Earth? If not, why not? O No, the thrust of the module's engines is less than its weight on Earth. O No, the thrust of the module's engines is equal to its weight on Earth. O Yes, the thrust of the module's engines is greater than its weight on Earth. O Yes, the thrust of the module's engines is equal to its weight on Earth.
