Final answer:
The given equation represents the height of a ball thrown upwards at time t. It takes into account the effect of gravity, initial velocity, and initial height of the ball.
Step-by-step explanation:
The subject of this question is Physics. The given equation s(t)=-16t² + 32t + 240 represents the height of a ball thrown upwards at time t in seconds. Momentum is not only conserved in mechanical systems but is also fundamental to understanding the behavior of both massive and massless particles, such as photons. In the equation, the term -16t² represents the effect of gravity on the ball, causing it to fall, while the term 32t represents the initial velocity of the ball. The constant term 240 represents the initial height of the ball.
