How much does a 45 kg rock weigh
bazaltina [42]

Answer:

441.45N

Explanation:

Weight = mass(kg) x acceleration (m/s^2)

Weight = 45kg x 9.81m/s^2=441.45N

Recall that weight =mass of the rock x gravitational force acting on the rock

Therefore, the rock will weigh = 441.45N

What is the mass of a football player if they are running at 3.6 m/s with a momentum of 62.5kgm/s?
ioda

momentum = mass * velocity

62.5 = mass * 3.6

mass = 62.5/3.6

Suppose you have an object tied to a rope and are rotating it over your head in uniform circular motion. What would have to do t
Crazy boy [7]

Answer:

We must duplicate the length of the rope (R'=2R) to get

F'=\frac{1}{2}F

Explanation:

The equation of the centripetal force is given by:

F_{c}=ma_{c}

F_{c}=m\frac{v^{2}}{R}

Where:

R is the length of the rope

m is the mass of the object

v is the speed of the object

If we want to reduce the centripetal force in half, we can duplicate the length of the rope (R'=2R), which means:

F'_{c}=m\frac{v^{2}}{R'}

F'_{c}=m\frac{v^{2}}{2R}

F'_{c}=\frac{1}{2}F_{c}

I hope it helps you!
