A student is getting ready to go on a bike ride, but her bike’s back tire is flat! She connects a pump to the valve and adds air
to the tire until it is fully inflated and ready to ride.
After the addition of air to the tire, the air pressure inside the tire is now __________ the air pressure outside the tire.

Answer:
We conclude that the kinetic energy of a 1.75 kg ball traveling at a speed of 54 m/s is 2551.5 J.
Explanation:
Given
- Mass m = 1.75 kg
- Velocity v = 54 m/s
To determine
Kinetic Energy (K.E) = ?
We know that a body can possess energy due to its movement — Kinetic Energy.
Kinetic Energy (K.E) can be determined using the formula
where
- m is the mass (kg)
- v is the velocity (m/s)
- K.E is the Kinetic Energy (J)
now substituting m = 1.75, and v = 54 in the formula
J
Therefore, the kinetic energy of a 1.75 kg ball traveling at a speed of 54 m/s is 2551.5 J.
