Let's examine over the next few questions an NFL kick as described in the 3rd Law video. The announcer claimed that the ball is

hichkok12 [17]

Answer:

8451.62109367671 Newtons

Explanation:

$1\ kg=1\times 9.8066500286389=9.8066500286389\ N$

$1 \lb=2.2046226218488\ kg$

It is known that

$1\ lbs=\dfrac{9.8066500286389}{2.2046226218488}=4.4482216282508\ N$

So,

$1900\ lbs=1900\times 4.4482216282508\\\Rightarrow 1900\ lbs=8451.6210936765\ N$

The force in Newtons is 8451.6210936765 Newtons

A car can go from 0 m/s to 38 m/s in 4.5 seconds. If a net force of 6570 N acted on

masha68 [24]

The Mass of the car = 782.1 Kg

The mass of the car is calculated as follows:

Mass = Force/ acceleration

The force on the car = 6570 N

The acceleration of the car, a = 38 - 0/4.5

acceleration = 8.44 m/s²

Mass of the car = 6570/8.44

Mass of the car = 782.1 Kg

In conclusion, the mass of the car is obtained from the acceleration and force on the car.
