A bus traveling at 24 m/s slows down to 12 m/s in 5.0 seconds. What is the acceleration?
Contact [7]

Answer:

a = -2.4 m/s²

Explanation:

Given,

The initial speed of the bus, u = 24 m/s

The final speed of bus, v = 12 m/s

Time taken to reach final speed is, t = 5.0 s

The acceleration of the body is given by the change in velocity by time

                                      a = (v - u) / t

                                         = (12 - 24) / 5

                                         = -2.4 m/s²

The negative sign in the acceleration indicates that the bus is decelerating.

Therefore, the acceleration of the bus is, a = -2.4 m/s²

What is true about an object in free fall?
salantis [7]
The only force being acted upon it is gravity. A ball that was thrown downward off a building isn't in freefall, because it had initial velocity. A piece of paper can't necessarily be in free fall because it is affected by air resistance.

A ball is moving at 4.5 m/s and has a momentum of 75 kg·m/s. What is the ball's mass?
chubhunter [2.5K]

Answer:

Mass = 16.67kg

Explanation:

Given the following data;

Velocity = 4.5m/s

Momentum = 75kgm/s

To find the mass;

Momentum can be defined as the multiplication (product) of the mass possessed by an object and its velocity. Momentum is considered to be a vector quantity because it has both magnitude and direction.

Mathematically, momentum is given by the formula;

Momentum = mass * velocity

Substituting into the equation, we have

75 = mass * 4.5

Mass = 75/4.5

Mass = 16.67kg

Therefore, the ball's mass is 16.67 kilograms.

Crazy boy [7]

Answer:

Low level jet

Explanation:

Jet streams can also form close to the earth's surface. of all such type of jet one jet  grows just over the main central plains of  United States, where speeds approaching 60 knots are rarely reached. This high point wind speed jet is recognised as low level jet, which typically comes from south or southwest.

As title indicates, , it termed as a rapidly-moving stream of air in low atmosphere levels .
