Answer:During the collision
Explanation:
When a baseball collides with bat its velocity changes from Positive To negative i.e. ball changes its direction to exactly opposite of initial. During collision at some point in time velocity of ball reaches zero and then finally changes its direction associated with an increase in velocity of the ball. velocity after depends upon the amount of force acting on the ball and the time of contact of force.
The following are four real life examples of the result of scientific investigation:
1. The development of the whole human genome.
2. The discovery of penicillin.
3. The discovery of a drug that cures tuberculosis.
4.The discovery that atoms have different energy levels and that electrons are found at each level.
All these events comes about as a result of scientific investigations.
Light to Electric to kinetic
The mass of the given object is 475 kg.
<h3>What is kinetic energy?</h3>
This is the energy possessed by an object due to its motion. The kinetic energy of an object in motion is given as;
K.E = ¹/₂mv²
where;
- m is the mass
- v is the velocity of the obeject
The mass of the object is calculated as follows;
Thus, the mass of the given object is 475 kg.
