I assume to give would be to spend a little longer catching the ball, this is done because the longer you take to change the velocity of something the less force you feel, another example of wanting to give would be a car crash, the longer you can absorb the hit the higher the chance of survival for the driver because the goal of giving in this scenario is to make the driver accelerate as slow as possible when crashing and a second example would be bending your knees when you fall because you make the time of impact longer reducing the amount of force you feel and also decreasing your odds of injury
Because high school usually starts with students who are above 13 years of age
Assuming the power delivered by the horse does not change, the speed of the cart will decrease.
In fact, the power delivered by the horse is the work done by the horse (W) per unit time (t):
<span>If several bags are added to the cart, the horse must do more work to transport them. Therefore, W in the fraction increases. But if the power P of the horse is constant, then it means that the time t must increase as well. So, the horse will take more time to transport the car, and this means that the speed of the cart has decreased.</span>
