Which of the following must be true about an object for it to be in uniform circular motion? A.It must have zero centripetal acc
Grace [21]

In the previous section, we defined circular motion. The simplest case of circular motion is uniform circular motion, where an object travels a circular path at a constant speed. Note that, unlike speed, the linear velocity of an object in circular motion is constantly changing because it is always changing direction. We know from kinematics that acceleration is a change in velocity, either in magnitude or in direction or both. Therefore, an object undergoing uniform circular motion is always accelerating, even though the magnitude of its velocity is constant.

An African elephant can heights of 4m and possess a mass of as much as 6000kg. Determine the weight of an African elephant in Ne
Alexandra [31]

The weight of the African elephant is 58,800 Newtons.

Explanation:

Step 1:

Mass of the African Elephant = 6000 Kg

We need to find the weight of  African elephant in Newton.

Step 2 :

Weight in Newtons = Mass of the object ×  acceleration due to gravity (g)

We know that value of  g is 9.8 m/sec²

Hence the required weight = 6000 × 9.8 = 58,800 Newtons

The height of the elephant can reach 4 m. But the weight of any object is nit dependent on the height and hence this information is not required to compute the weight.

Step 3 :

Answer :

The weight of the African elephant is 58,800 Newtons.

If an object is moving at 2m/s towards a porcelain vase, do you think it will have enough momentum to brake the vase?
Alex Ar [27]

Answer: No

Explanation:

Momentum p refers to how much force is needed to change the motion of a body or object by changing its direction or braking it. In addition, momentum is directly proportional to the mass m and the velocity v:

p=mv

Now, assuming both the object and the porcelain vase have the same velocity v=2m/s but different mass, and assuming the mass of the vase is greater than the mass of the object; the momentum of the porcelain vase will be also greater than the momentum of the object.

Hence, the object will not have enough momentum to brake the vase.
