Taking into account air resistance, how do you throw a ball to get the maximum range? Why?
A ball rolls in a straight line along the horizontal direction. Using motion diagrams (or multi flash photo-graphs), describe the velocity and acceleration of the ball for each of the following situations: (a) The ball moves to the right at a constant speed, (b) The ball moves from right to left and continually slows down, (c) The ball moves from right to left and continually speeds up. (d) The ball moves to the right, first speeding up at a constant rate and then slowing down at a constant rate.
A father demonstrates projectile motion to his children by placing a pea on his forks handle and rapidly depressing the curved tines, launching the pea to heights above the dining room table. Suppose the pea is launched at 8.25 m/s at an angle of 75.0 above the table. With what speed does the pea strike the ceiling 2.00 in above the table?

1.On August 25,1894, Chicago catcher William Schriver caught a baseballthrown from the top of the Washington Monument (555 ft, 898steps). (a) If the ball was thrown horizontally with a speed of5.00 m/s, where did it land? (b) What were the ball’s speed anddirection of motion when caught? Graph and Explain.
1.A 2.05-mm-tall basketball player takes a shot when he is 6.02 mmfrom the basket (at the three-point line). If the launch angle is 23 ∘∘ and the ball was launched at the level of the player’s head, what must be the release speed of the ball for the player to make the shot? The basket is 3.05 mm above the floor. v= 2.This time, William Tell is shooting at an apple that hangs on a tree (see the figure (Figure 1)). The apple is a horizontal distance of 20.0 mm away and at a height of 4.00 mm above the ground. If the arrow is released from a height of 1.00 mm above the ground and hits the apple 0.590 ss later, what is the arrow’s initial speed? 3.Awheeled car with a spring-loaded cannon fires a metal ball vertically If the vertical initial speed of the ball is 2.0 m/sm/s as the cannon moves horizontally at a speed of 0.65 m/sm/s , how far from the launch point does the ball fall back into the cannon? What would happen if the cannon were accelerating?
I'm not sure how to solve this! I tried and got 1.3 / 2.4 seconds. Am i right? Could you explain how to do it if i'm not? Cheers ! In a classic Seinfeld episode, Jerry tosses a loaf of bread (a marble rye) straight upward to his friend George who is leaning out of a third-story window. If the loaf of bread leaves Jerry's hand at a height of 1 m with an initial velocity of 18 m/sec, write an equation for the vertical position of the bread s (in meters) t seconds after release. How long will it take the bread to reach George if he catches the bread on the way up at a height of 16 m? Round to the nearest tenth of a second.
4. Indicate which quantities are vectors and which are scalar 5. To guarantee that this car can break the latest rally records, the owner decided to make simplecalculations to check the time needed to drive the racing distance, the equation he remembersfrom the old school days in the physics course when he was a student is:Xf = Xi + V* t+0.5 a*tWhere: xf, xi are the final and initial positions relatively, v is the velocity, a is the acceleration andt is the time. Prove to the owner that the equation he will use is dimensionally incorrect 6. If the kinetic energy (kg.m2 /S2) is given by the equation m x * v y calculate the values of x and ywhich make the equation dimensionally correct
10 - A ball is launched from a height of 30 m downwards with an initial velocity of 15 m / s. After how many seconds does it hit the ground?A) 4.44B) 3C) 1.25D) 1.38E) 2
3) You throw a ball straight up. The ball leaves your hand at a height of 2.00 m above the ground with a speed of 20.0 m/s (~45 mph). Ignore air resistance and use g = 10.0 m/s2. You can use a spreadsheet but show a sample calculation for the velocity and the position at t = 1.5 s. 3a.) Calculate and make a table of the height, y(t), and y-velocity, vy(t), at 0.50-second intervals until the ball hits the ground. Your table should have the units in the column headers: t (s), vy (m/s), y (m) Remember to add the ysubscripts when the motion is along the y-axis. 3b.) Use this data to draw a motion diagram for the ball at 0.50-second intervals. Label the time, y-coordinate,and the velocity at each time interval. Label the origin, starting height, maximum height, and final height.Include the instantaneous velocity vectors at each time and location of the ball. 3c.) Calculate the time it takes for the ball to hit the ground and the final velocity of the ball just as it hits the ground.…
