What are the forces that act on the ball?​

Physics
1 answer:
scoundrel [369]3 years ago
4 0

Answer:

This slide shows the three forces that act on a baseball in flight. The forces are the weight, drag, and lift. Lift and drag are actually two components of a single aerodynamic force acting on the ball. Drag acts in a direction opposite to the motion, and lift acts perpendicular to the motion

Gravity __________ your kinetic energy when you are driving uphill and __________it when you are driving downhill.
Oxana [17]
Gravity decreases your kinetic energy when you are driving uphill since the direction of motion is opposite for both. Driving uphill is force going upward while gravity pulls object down. When it is going downhill, the car tends to go faster since the gravity helps the object to go down by adding another value to the total acceleration of the motion of the object. Using the forces of balance, an object going up tends to become heavier while object going down tends to become lighter because of the gravity factor. Another analogy is the motion of elevators going up and down that incurs effects to your weiight.

In 1985, there were 285 cell phone subscribers in the small town of Glenwood. The number of subscribers increased by 75% per yea
Amiraneli [1.4K]

Answer:

b. (4677)

Explanation:

You can apply the same equation we use to calculate the compound interest but with phones.

Look:

M = C.(1+i)^n

M = the total amount after 5 years

C = the firts amout of phones (285)

i = how much this number gets bigger (75%)

n = the number of periods (5 years)

So...

M = 285 . (1 + 0,75)^5

M = 285 . 1,75^5

M = 285 . 16.4

M = 4677
