A service elevator takes a load of garbage, mass 10.0 kg, from a floor of a skyscraper under construction, down to ground level,
kobusy [5.1K]

Answer:

The magnitude of the force the garbage exerts on the floor of the service elevator is 12 N

Explanation:

Given;

mass of the garbage, m = 10.0 kg

acceleration of the elevator, a = 1.2 m/s²

The magnitude of the force the garbage exerts on the floor of the service elevator is given by;

F = ma

F = 10 x 1.2

F = 12 N

Therefore, the magnitude of the force the garbage exerts on the floor of the service elevator is 12 N

A 80kg cart goes around the inside of a vertical loop of a roller coaste. The radius of the loop is 5m and the cart moves at a s
amid [387]

Answer:

F = 1024 N

Explanation:

Given that,

Mass of the cart, m = 80 kg

Radius of the loop, r = 5 m

Speed of the cart, v = 8 m/s

To find,

the force exerted on the track on the cart.

Solution,

The force exerted on the track on the cart is called centripetal force. When an object moves in a circular path it possess centripetal force. It is given by :

F=\dfrac{mv^2}{r}

F=\dfrac{80\times (8)^2}{5}

F = 1024 N

So, the  force exerted on the track on the cart is 1024 N.
