Projectile Motion basketball shot

Click For Summary
The discussion focuses on calculating the initial resultant velocity of a basketball shot and the maximum height reached by the ball. The player shoots from a distance of 15 meters at a 55-degree angle, with the hoop height set at 3 meters. Trigonometric principles are suggested for rearranging equations to find the initial velocity. Participants express gratitude for the guidance provided in solving the problem. Understanding projectile motion is essential for accurately determining these values in basketball scenarios.

eek.
I need help.

A basketball player shoots a basketball into a hoop to score a "point". The height of the hoop is 3m. The shooter stands 15 m from the basket and shoots the ball at a 55 degree andle from the horizontal. Assume the height of player is 0.

Need to find:
1) The baslketball's initial resultant velocity.
2) The maximum height of the basketball.

I think you need to use trigonometry and rearrange the equation for the horizontal component (because you have been given it) to get the inital resultant velocity (u).
hope that gives you a start

that helped alot! thanks
 
The book claims the answer is that all the magnitudes are the same because "the gravitational force on the penguin is the same". I'm having trouble understanding this. I thought the buoyant force was equal to the weight of the fluid displaced. Weight depends on mass which depends on density. Therefore, due to the differing densities the buoyant force will be different in each case? Is this incorrect?
