Akbar and Lucia apply opposing forces on a

Physics
1 answer:
iragen [17]3 years ago
3 0

Answer:

20 N

Explanation:

We can solve this problem by applying Newton's second law of motion, which states that the net force applied on an object is equal to the product between the mass of the object and its acceleration:

F=ma

where

F is the net force

m is the mass

a is the acceleration

In this problem, we have:

m = 10 kg is the mass of the cart

a=2 m/s^2 is the acceleration

So the net force on the car is

F=(10)(2)=20 N

Since Lucia and Akbar are pushing into opposite directions, this means that this net force is the resultant of the two forces: and since the cart is accelerating towards Akbar, this means that Lucia is applying a force 20 N stronger than Akbar.

To move a heavy object, like a refrigerator what could be used to help decrease the frictional force?
Olenka [21]

Answer:

A. Remove everything in the refrigerator to lighten the load.

B. Put a lubricant between the surface of the object and the floor

C. Use round objects, like pencils , to decrease the friction and push the refrigerator over the pencils more easily

Explanation:

Force of friction is a resistance force which acts between two surfaces which are in relative motion. Friction is both boon and bane. Due to friction, we are able to sit, walk etc but also, due to friction there is dissipation of energy. Friction can be reduced by applying lubricants, reducing contact area, reducing the load.

F = μN where N is the normal force which depends on the mass.

Thus, by reducing the load, force of friction can be reduced. Round objects like wheels can also be used. By this the contact area reduces.

A descent vehicle landing on the moon has a vertical velocity toward the surface of the moon of 29.6 m/s. At the same time, it h
inessss [21]

If the vertical component is 29.6 m/s down, and the horizontal component
is 54.8 m/s parallel to the surface, then the magnitude of the slanty vector is

   √(29.6² + 54.8²) = √(876.16 + 3003.04) = √3879.2  =  62.28 m/s .

That's 139 mph !  Wow !
