Final answer:
When the man is jumping through the air, the forces on him are unbalanced due to gravity constantly pulling him down, while the upward force from his jump is temporary. After the peak of his jump, gravity will cause him to fall back down and land on a surface.
Step-by-step explanation:
If a man is jumping through the air, the forces on him are unbalanced. The primary forces acting on the man are gravity, which pulls him downwards, and the initial upward force from jumping. The force of gravity is constant, while the upward force from the jump is a one-time force that gives him an initial velocity upwards. Once the upward force has been applied and the man is airborne, there are no additional upward forces to counteract gravity, creating an unbalanced force situation that results in a downward acceleration.
After the photo of the man jumping was taken, what likely happened is him reaching the peak of his jump, where the upward velocity is zero, and then beginning to fall back down due to the force of gravity. Eventually, he would land on the ground or another surface.
Forces Acting on the Man
- Force of Gravity (downward)
- Initial Upward Force (from jumping)
These unbalanced forces would result in the man rising to the peak of the jump before gravity pulls him back down, leading to a downward movement until he lands back on a surface.
