- A 150g baseball is thrown directly upwards with a velocity of 20.0m/s. 1.00 second later an 8.00g bullet is fired upwards at the baseball with a velocity of 300m/s. The bullet collides and embeds itself in the ball. Find the maximum height of the bullet/ball pair.10. A poolio-coolio claims that he has perfected the greatest trick shot of all time. He claims that he can arrange three pool balls in the center of the table such that when he hits them with the cue ball some extraspecialness happens. He claims that the cue ball comes to rest, two of the balls move directly away from each other along a line perpendicular to the direction of the incoming cue ballI, and the remaining ball moves in the direction of the cue balls original path. All of the balls involved have the same mass. Using your cunning physics prowess, prove that he is full of hot air. Hint: You will need to use momentum and kinetic energy.What is a projectile? Give two examples?
- A firecracker moves vertically upward and after reaching the highest point in its vertical trajectory, it starts falling down. After it falls down by 17.7 meters in air it cracks into two identical pieces. One of the pieces shoots off horizontally with 11.8 m/s speed. What would be the magnitude of the velocity of the other piece right after they split? Enter your answer in m/s. On your paper, show both your calculation for the magnitude and also the direction of the velocity vector of the second piece. Show your work in detail including your physics- based reasoning.5. Three objects of the same mass are launched separately at different angles (30, 45 and 60). Which of the three will have the longest range provided they have the same initial velocity? Why? 6. What will happen to the range and height of the projectile if you put a value of air resistance? Why?Find the impact velocity of the ball and verify if it is a homerun. Use PARAMETRIC EQUATIONS and make a graph of the trajectory of the ball.
- Stephen Curry passed the ball to Kevin Durant. Durant let the ball bounce before getting the ball for the dunk. The ball bounced with a velocity of 8.5 m/s at an angle of 70°. a. Find the x-component (horizontal) of the initial velocity, b. And the y-component (vertical) of the initial velocity. Assume that Kevin Durant did not get ball from the first bounce. c. Find the Maximum height of the ball d. Find the range (distance in x direction) of the ball after the first bounce? e. How long is the ball in the air after the first bounceTwo rolling carts are moving toward each other at the same speed. Cart 1 has a mass m1 =200g and Cart 2 has a mass m2 =400g. Draw a velocity vector v → for each cart. Momentum p → is a vector defined as p → = m v →. Draw a momentum vector for each cart. Then add the two momentum vectors together to find the total momentum, vector P total =vector p1 + vector p2IM-5 Jae throws a 0.350kg ball so that it is traveling at 7.50m/s y toward a wall, approaching the wall at an angle of 35.0° as shown in the figure to the right. After hitting the wall, the speed of the ball is still 7.50m/s but its direction has changed and it is now traveling at an angle of 35.0° away from the wall as shown to the right. a) Sketch on your paper a figure like the one shown to the right and show the vectors for the momentum before impact, PB, the momentum after impact, PA, and use them to find Ap, the change in momentum for the ball. Clearly label each vector. b) Calculate the sign and magnitude of Apx. the change in momentum in the x direction. c) Calculate the sign and magnitude of Apy the change in momentum in the y direction. d) If the collision lasts for 0.150 seconds, find the magnitude of the average force on the ball during the collision. What is the direction of the average force on the ball during the collision? Answer this by showing an arrow and label it as…
- 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…A cannon is on the edge of a vertical cliff 50 m high. The cannon then fires horizontally giving the cannon ball a speed of 420 m/s. What is the speed of impact (in m/s) of the cannon ball? A. 420. B. 423. C. 432. D. 440. E. 437At the instant a horizontally projected object is launched, an identical object is dropped. Which object will hit the ground first, the one projected horizontally or the one dropped? Be sure to explain fully, addressing the relevant underlying material.
