Present at least one example that illustrates acceleration. Is this a scalar or vector quantity? Explain why. ...?
SIZIF [17.4K]
Acceleration is a vector because it has magnitude and direction

Example :
a Car stopping at the rate of 5 m/s. In this example, the direction of acceleration is the opposite of the direction of velocity, and the magnitude is 5 m/s

Hope this helps

A baseball (m = 145 g) approaches a bat horizontally at a speed of 38.9 m/s (87 mi/h) and is hit straight back at a speed of 45.
leva [86]

Answer:

Fav = -12209 N

Explanation:

let p1 be the initial momentum of the ball and p2 be the final momentum of the ball. let v1 be the initial velocity of the ball and v2  be the final velocity of the ball.

From Newton's second law of motion, we get that the avarage force acting on the ball is given by:

Fav = Δp/t

      = (p2 - p1)/t

      = m(v2 - v1)/t

      = [(145×10^-3)(-45.3 - 38.9)/(1×10^-3)

      = - 12209 N

Therefore, the average force applies on the ball by tha bat is 12209 in the direction opposite to the balls initial direction.

Suppose a person has a small intestine that has fewer villi than normal. Would the person most likely be overweight or underweig
Mekhanik [1.2K]
They would be likely to be underweight. This is because the role of villi is to increase absorption of soluble molecules, they do this by increasing surface area for absorption to occur across.
If the person has less villi than normal in their small intestine, then the surface area will not be as large meaning there is less area for absorption to occur across so less soluble molecules will be absorbed.
