Can you have a positive velocity but a negative acceleration? I need this to complete my physics hw :/

1 answer:

8 0

Answer: Positive velocity is then speed towards right, and negative velocity is speed towards left. It is the same for acceleration: negative acceleration is acceleration towards left. It slows objects moving towards right

Explanation: In physics calculations, acceleration — just like displacement and velocity — can be positive or negative. can u help me now pls ?

If a force of 450N pushes a box 4 meters in 2 seconds, how much power was developed?

strojnjashka [21]

Work = (force) x (distance) = (450 N) x (4 m) = 1,800 joules

Power = (work) / (time) = (1,800 joules) / (2 sec) = 900 watts .

a mango drops to the ground from the top of a tree which is 5 meter high,how does it take the mango to reach the ground

tatuchka [14]

Gravity tends to pull the object towards the earth's surface, resulting in a drop or a free fall. Fruits falling from a tree, a stone thrown off a cliff, skydiving, and other free-fall motions are examples.

Mango takes 1.009 seconds to reach the ground.

A situation in which an object moves solely under the influence of gravity is referred to as free fall. An external force acts on the ball, causing it to move faster. This free fall acceleration is also known as gravitational acceleration. The term "free fall" refers to a downward movement with no initial force or velocity.
Gravity tends to pull the object towards the earth's surface, resulting in a drop or a free fall. Fruits falling from a tree, a stone thrown off a cliff, skydiving, and other free-fall motions are examples.

h = $\frac{g t^2}{2}$

where,

h = height = 5m ,

t = time ,

g =gravity = 9.8 m/s.

$t^{2}$ = 2h / g = 10/9.8 = 1.02

t= $\sqrt{1.02}$ = 1.009 sec

ICD-10-CM codes are -S02.2XXA, W21.01XA, Y93.61, Y92.830

S02.2 for Fracture, Traumatic/Nasal (Bone(s)), ICD-10-CM Alphabetic Index. Both the open fracture code and the dislocation code are not reported. Only the fracture code is provided if a fracture and a dislocation happen at the same place. Search for "dislocation/with fracture" in the alphabetical index to be sent to a doctor. A closed fracture is a fracture with displacement. To report the conditions leading up to the injury, external cause codes are utilized. Look for Struck (accidentally) by/ball (struck) (thrown)/football W21.01 in the ICD-10-CM External Cause of Injuries Index. Seven characters are required in the Tabular List to finish the code. For the first encounter, X is utilized as a stand-in for character number six, and character number seven is given the letter A.
