Question

The cart now moves toward the left with an acceleration toward the lkeft of 2.50 m/ft^3. What does spring scale F_ read? Show your calculations and explain. Ben is of the bull moose is use the large mass of the moose to his own motion extremely intimidating. Yet, if Ben makes a zigzag pattern through the woods, he will be able to s advantage. Explain this in terms of inertia and Newton's first law of 2. If you're in a car at rest that gets hit from behind you can suffer a serious neck injury called whiplash. What does whiplash have to do with Newton's Is law? 3. Suppose that there are two seemingly identical bricks at rest on the physics lecture table. One brick consists of mortar and the other brick consists of Styrofoam. Without lifting the bricks, how could you tell which brick was Styrofoam brick?
Need help with questions 1-3 please

Answer 1

1.Mass is heavy means inertia will be more.If he moves zig zag the haevy mass cant change its state duecto high inertia of direction.

2)Inertia of rest. When we r suddenly hit by other object when sitting in car,the body attached to seat will try to move with car but the head part cant. So severe neck injury takes place.

3)different weights have different normal reactions
