Final answer:
The problem involves calculating a basketball player's velocity and acceleration during a jump, as well as the force exerted on the floor. Using kinematic equations and Newton's second law, we can find the velocity, acceleration, and force based on the given distances and the player's mass.
Step-by-step explanation:
To solve the problem involving Angela playing basketball and focusing on acceleration and speed, we need to apply the concepts of kinematics in physics.
Step-by-step Solution
- First, we understand that the player descends 0.300 m and jumps 0.900 m. Using the kinematic equation for free fall (v^2 = u^2 + 2as), where v is the final velocity, u is the initial velocity (zero in this case), a is acceleration, and s is the distance (0.900 m), we can calculate the velocity at the point the player leaves the floor.
- Once we have the velocity, we can use it to find the acceleration during the leg straightening phase using the same kinematic equation but with 0.300 m as the distance.
- Lastly, to find the force exerted, we use Newton's second law of motion (F=ma), where F is the force, and m is the player's mass (110 kg). By plugging in the mass and the acceleration found in step 2, we obtain the force exerted on the floor.
