Physics

The final velocity of the ball is16.66 m/s.

<u>Given the following data:</u>

  • Initial velocity, U = 0 m/s (since the ball is falling from rest).
  • Time, t = 1.70 seconds.

We know that acceleration due to gravity (a) for a ball in free fall is equal to 9.8 meter per seconds square.

To find how fast (velocity) the ball is moving, we would use the first equation of motion:

Mathematically, the first equation of motion is calculated by using the formula;

V = U + at

<u>Where:</u>

  • V is the final velocity.
  • U is the initial velocity.
  • a is the acceleration.
  • t is the time measured in seconds.

Substituting the given parameters into the formula, we have;

V = 0 + 9.8(1.7)

V = 9.8 × 1.70

<em>Final velocity, V </em><em>= </em><em>16.66 m/s.</em>

Therefore, the final velocity of the ball is16.66 m/s.

For every action, there is an equal and opposite reaction” is a definition of _________ ​
sveticcg [70]

Answer:

These two forces are called action and reaction forces and are the subject of Newton's third law of motion. Formally stated, Newton's third law is: For every action, there is an equal and opposite reaction. The statement means that in every interaction, there is a pair of forces acting on the two interacting objects.

The muzzle velocity of a bullet fired from a new rifle is 100 m/s. Neglecting air resistance, at the end of one second a bullet
Burka [1]

Answer:

C. (100+4.9)m

Explanation:

u = 100m/s, t = 1 sec, g = 9.8m/s^2

s = ut + 1/2gt^2

s = 100×1 + 1/2×9.8×1^2 = 100+4.9

s = (100+4.9)m
