The acceleration of the baseball is:
where
and
are the final and initial speed of the ball, and
is the time interval in which the force acted.
Replacing the numbers, we get
And at this point, we can use Newton's second law F=ma to find the value of the force of the pitching machine:
The mass of a school bus if it can accelerate from rest to 15.5 m/s over 8.25s with 7,500 N of force is 3989.4kg.
HOW TO CALCULATE MASS:
- The mass of an object can be calculated by dividing the force applied to the object by its acceleration.
- According to this question, a bus can accelerate from rest to 15.5 m/s over 8.25s. The acceleration can be calculated as follows:
- The mass of the bus = 7500N ÷ 1.88m/s²
- The mass of the bus = 3989.4kg
- Therefore, the mass of a school bus if it can accelerate from rest to 15.5 m/s over 8.25s with 7,500 N of force is 3989.4kg.

The answer that would best complete the given sentence above is cubic meter. The standard unit for measuring volume is the cubic meter (m^3). Volume is the quantity or the measurement of the amount of space that can be or is being occupied by matter. The metric unit for volume includes "liters" and "milliliters".
Answer:
law stating that the ratio of the sines of the angles of incidence and refraction of a wave are constant when it passes between two given media.
Snell's law, in optics, a relationship between the path taken by a ray of light in crossing the boundary or surface of separation between two contacting substances and the refractive index of each. ... Snell's law asserts that n1/n2 = sin α2/sin α1.
