The instant it was dropped, the ball had zero speed.

After falling for 1 second, its speed was 9.8 m/s straight down (gravity).

Its AVERAGE speed for that 1 second was (1/2) (0 + 9.8) = 4.9 m/s.

Falling for 1 second at an average speed of 4.9 m/s, is covered <em>4.9 meters</em>.

ANYTHING you drop does that, if air resistance doesn't hold it back.

A 1420-kg car is traveling with a speed of 12.4 m/s. What is the magnitude of the horizontal net force that is required to bring
zzz [600]

Answer:

1419.01436 N

Explanation:

t = Time taken

u = Initial velocity

v = Final velocity

s = Displacement

a = Acceleration

v^2-u^2=2as\\\Rightarrow a=\frac{v^2-u^2}{2s}\\\Rightarrow a=\frac{0^2-12.4^2}{2\times 78}\\\Rightarrow a=-0.98564\ m/s^2

The force on the car

F=ma\\\Rightarrow F=1420\times -0.98564\\\Rightarrow F=-1419.01436\ N

Magnitude of the horizontal net force that is required to bring the car to a halt is 1419.01436 N

7. If F1 is the magnitude of the force exerted by the Earth on a satellite in orbit about the Earth and F2 is the magnitude of t
natita [175]

Answer:

F1 is equal to F2            

Explanation:

Here

F1 is the gravitational force exerted by the earth on the satellite.

F2 is the gravitational force exerted by the satellite on the earth.

Now these two forces are equal but opposite in nature. This is given by the Third law of motion by Newton. According to this law, when there is force exerted between two objects, one force is balanced the other force which is equal in magnitude and opposite in nature.

Thus the gravitational force of the earth exerted on the satellite is equal to the force exerted by the satellite on the earth.

Hence F1 = F2.
