Answer:

We will go in the same direction where the car was was moving before applying brakes

Our speed will be same as that of speed of the car before applying brakes i.e. 30 mph

This is due to law of inertia as we are initially moving with speed 30 mph so the due to inertia of motion of our body after applying brakes we move in the same direction.

Explanation:

As we know by Newton's first law that every object moves in its state of motion or state of rest until and unless some external force will act upon it.

Here we know that car is initially moving with speed 30 mph so our body has state of motion so it will have tendency to move in same direction.

Here when brakes are applied in the car then also our body will move with same speed in same direction due to inertia of motion.

So our body will strike with windshield with the speed of 30 mph.

A ball is thrown vertically upward. As it rises, what happens to its total energy?.
diamong [38]

The total energy of a ball stays constant as it is thrown upward because potential energy increases while kinetic energy decreases. When the ball reaches its maximum height, the velocity is zero. Therefore, only potential energy exists rather than kinetic energy.

The thrower's movement imparts kinetic energy to a ball thrown vertically. The maximum height that can be achieved after leaving the hand will depend on the actual velocity. Air resistance causes some of this energy to be lost to the air as frictional dissipation, which warms the air in the area as well as the ball's surface.

We can just talk about how the ball moves when it is in the gravitational field of the Earth if we ignore this for the purposes of this discussion. The ball's total energy as it is released is comprised of both its gravitational potential energy and its kinetic energy, which result from the ball's velocity (due to its position).

The gravitational potential energy begins to rise as the ball moves vertically upward at precisely the same pace as it loses kinetic energy. The ball experiences a steady downward acceleration of 9.81 m/s2, which causes it to initially decline until it briefly comes to a stop at its highest point.

Due to its current position in the Earth's gravitational field relative to its initial position, all of the energy at this point is gravitational potential energy. As the ball experiences constant downward acceleration, its motion immediately becomes apparent in that direction because the acceleration easily transforms gravitational potential energy back into kinetic energy.

As a result, at every point along the trajectory, the total of these interchangeable forms of energy remains constant.

If earth did not rotate how would air at the equator move?
Dmitry_Shevchenko [17]
Heat rises, and it is warmer at the equator, so I think warm air would rise at the equator and move towards the cooler poles.
