I need help with question 8
The scopeContext
A child's toy module rolls a marble through a pipe and then launches it into the air. An exasperated dad looking for the lost marbles all over the house asks you for help in calculating where the marble will fall and the size of the basket he should place there to be sure to catch the ball.
Constraints
The muzzle velocity and angle of fire depend on the construction the children make;The ball is fired from the ground and will land at ground level;The thickness of the basket itself is neglected.
Modelization
Create a model to calculate the distance from where the ball is shot to where the center of the basket would need to be to catch it, based on the speed and angle of the shot, as well as the uncertainty on these two parameters.
HINT for uncertainty: when the equation contains increasing and decreasing functions (such as sine and cosine, for example), it is necessary to proceed by trial and error to find the maximum and the minimum. A parameter cannot have two…

- If the ball is fired horizontally the time of travel doesn't depend on its speed.arrow_forwardA mortar is like a small cannon that launches shells at steep angles. A mortar crew is positioned near the top of a steep hill. Enemy forces are charging up the hill and it is necessary for the crew to spring into action. Angling the mortar at an angle of 0 65.0° (as shown), the crew fires the shell at a muzzle velocity of 148 ft/s. How far d down the hill does the shell strike if the hill d subtends an angle o = 37.0° from the horizontal?

Under International Basketball Federation (FIBA) rules, the three-point line is 6.75 meters from the center of the basket. If he will train for three-point shooting, what should be the ball's angle when he shoots the ball if he will try to shoot from a height as high as the basket with an initial velocity of 8.2 m/s? Is it 40°; 50°; 60°? How long would it take for the ball to reach the ring for each of the angles? What is the ball's maximum height for each of the angles? And how fast is the ball's horizontal and vertical initial velocities for each or the angles?arrow_forward
- An outfielder throws a baseball to his catcher in an attempt to throw out a runner at home plate. The ball bounces once before reaching the catcher. Assume the angle at which the bounced ball leaves the ground is the same as the angle at which the outfielder threw it as shown in above figure, but that the balls speed after the bounce is one-half of what it was before the bounce. (a) Assume the ball is always thrown with the same initial speed and ignore air resistance. At what angle u should the fielder throw the ball to make it go the same distance D with one bounce (blue path) as a ball thrown upward at 45.0 with no bounce (green path)?
