- Can you help me answer this? Solve separately by letter and explain how you get the answer. Thank you. About projectile motion.I asked the question here before but the solution was wrong. that's why I will ask again. Sam and William are playing with a ball. Sam throws the ball 30 s after William started to run away from the starting position. If William is accelerating 1.6 m/s2 starting from rest, find the initial velocity of the ball to hit the moving target and the ground at the same time. The ball is thrown 1.5 m from the ground and 46° from the horizontal. Choices: a. 112 m/s b. 126 m/s c. 163 m/s d. 143 m/sPlease view the picture to be able to answer the question: Question: What is the magnitide of his average velocity? a. 5 m/s b. 0 m/s c. 0.75 m/s d. 2.25 m/s
- A basketball player shoots toward a basket 5 m away and 3.0 m above the floor. If the ball is released 1.8 m above the floor at an angle of 52 degrees above the horizontal, what must the initial speed be if it were to go through the basket? Write your answer in m/s with one decimal place. To keep full credit or gain partial credit, you must upload your work in the final question of the midterm.The brakes are applied to a moving car, causing it to uniformly slow down. While slowing, it moves a distance of 40.0 m in 7.40 s to a final velocity of 1.50 m/s, at which point the brakes are released. What was its initial speed (in m/s), just before the brakes were applied? What was its acceleration (in m/s2) while the brakes were applied? (Assume the initial direction of motion is the positive direction. Indicate the direction with the sign of your answer.)A baseball player uses a very massive golden bat to hit a rubber ball off of a tee. If the bat is moving 20 m/s when it hits the ball, what will be the speed of the ball as it leaves the bat? (Hint: What change of ball velocity would a flea see while riding on the bat, thinking it to be stationary?) Give your answer in m/s but do not write the units.
- Answer the following questions: One day after school, you are enjoying a soda in the back yard. When the can is empty, you decide to throw it in the trashcan. What effects whether or not it gets in the can? Use Projectile Motion to test your ideas about the things that affect the landing location of a projectile. Make a complete list of things that affect the landing site of a projectile including your ideas from question #1 and any discoveries you made using the simulation. Next to each item, briefly explain why you think the landing location changes. What is meant by the expression "flight path of a projectile"? Draw (or explain) the flight of the soda can. Use the simulation to investigate how the items listed in #2 affect the flight path. Summarize your discoveries including explanations for the different flight paths.

- From the FBD what do you think is happening? Is the object speeding up or slowing down or is it at rest or is falling?Based on the attached photo, what is the acceleration when t=3s? Please show complete and proper solutionYou're heading an international effort to save Earth from an asteroid heading toward us at 11 km/s. Your team mounts a rocket on the asteroid and fires it for 10 min, after which the asteroid is moving at 21 km/s at 32° to its original path. In a news conference, what do you report for the acceleration imparted to the asteroid? (Express your answers using two significant figures separated by a comma. Assume that the positive x-axis is in the direction of the initial motion of asteroid and y-axis is perpendicular to it.)
