QUESTION How would the answer to part (b), the maximum height, change if the person throwing the ball jumped upward at the instant he released the ball? The maximum height would decrease. The maximum height would remain the same. The maximum height would increase. Consider how the initial velocity of the ball relative to the ground is affected...

While walking, you often make horizontal turns. Imagine making a right horizontal turn along a circular path, with diameter of 0.25 m. If you are walking 3.8, without slipping, determine the net external force you must experience to negotiate the turn. (Assume your mass is 98 kg.) MOSS-98 situs i. 1490 N 0.251 0.25m-dia (ii. 2980 N iii. 5660 N iv. 11300 N v. There is not enough information to solve...

Catch Julie throws a ball to her friend Sarah. The ball leaves Julie's hand a distance 1.5 meters above the ground with an initial speed of 14 m/s at an angle 60 degrees; with respect to the horizontal. Sarah catches the ball 1.5 meters above the ground. 1) What is the horizontal component of the ball's velocity when it leaves Julie's hand? 7 /s Submit 2) What is...

A stone is thrown upwards from the top of a building an initial height 11 m above the ground with a velocity of 6 m/s. (4 marks) Calculate i) The maximum height above the building the stone reaches ii) The time it takes the stone to hit the ground iii) The distance the stone travels iv) The displacement the stone undergoes

1. I this problem, assume that the positive y direction points up and that y 0 at the ground. For a ball in (i) Draw a free body diagram, showing all of the forces acting on the ball, and find an expression for the acceleration of the ball. (i) Determine whether the position of the ball is positive, negative, or zero. (iii) Determine whether the velocity of the ball is positive, negative, or zero. (iv) Determine whether the acceleration of...

please help am doubting my analysis
i. Solve the following problem on a clean sheet of paper. A cannon shoots a cannonball from the ground level (ignore the height of the cannon) towards a cliff of height h = 170 m. The cannonball is launched with an initial velocity of 110 m/s at an angle of 64° above the horizontal. Neglect air resistance. Assume the cannonball hits the cliff as it descends (on its way down) exactly at the edge,...

Problem 2: I throw a ball, mass m-5.0kg, at an initial speed of 3.0m/s, at an initial height of 1.7m, but at an angle of 37' with respect to the horizontal. It lands on the ground, at a final height of zero. (a) What is the initial velocity? (This is a VECTOR. Define ti as the horizontal, and +j as the vertical.) (b) What is the time when the ball obtains its maximum height? (c) What is the maximum height...
