Given: A ball with a mass of 1 Kg is released from rest at point A and rolls down a quarter circle reaching point B. The ball leaves point B with a horizontal velocity, Vb and undergoes projectile motion. At point C the player headbutts the ball with a force of 1,000 N above the horizontal and the point of impact lasts t = 0.005 (sec). Ignoring air resistance, the work done by friction from points A to B is -20 J.
Find: After the player hits the ball at point C, what is the ball's highest point and how long does it take the ball to reach the horizontal (x-axis)? How much distance was covered?

- You drop a 2.50 kg book to a friend who stands on the ground at distance D-13.0 m below. If your friend's outstretched hands are at distance d-1.60 m above the ground (see the figure), (a) how much work W, does the gravitational force do on the book as it drops to her hands? (b) What is the change AU in the gravitational potential energy of the book-Earth system during the drop? If the gravitational potential energy U of that system is taken to be zero at ground level, what is U (c) when the book is released and (d) when it reaches her hands? Now take U to be 100 J at ground level and again find (e) W. (f) AU, (g) U at the release point, and (h) U at her hands. 10000 ElA 1.80 kg snowball is fired from a cliff 12.0 m high. The snowball's initial velocity is 16.4 m/s, directed 27.0° above the horizontal. (a) How much work is done on the snowball by the gravitational force during its flight to the flat ground below the cliff? (b) What is the change in the gravitational potential energy of the snowball-Earth system during the flight? (c) If that gravitational potential energy is taken to be zero at the height of the cliff, what is its value when the snowball reaches the ground? (a) Number (b) Number (c) Number Units Units Units86. Consider a particle on which several forces act, one of which is known to be constant in time: F₁ = (3N)Î + (4N)Ĵ. As a result, the particle moves first along the x-axis from x = 0 to x = 5 m and then parallel to the y-axis from y = 0 to y = 6 m. What is the work done by F?
- Can someone help with second question? ThanksKindly provide the solution to the following question using the GRASS method. Work and Energy question, (Unit: Energy and Momentum): While cleaning out the basement of your parents you come across a box of old toys with Transformers and GI Joes. You push the box along a smooth level surface with a force of 35 N at an angle of 25° below horizontal. If the box is accelerated from a speed of 0.60 m/s to 1.45 m/s over a distance of 3.5 m, what is the mass of the box? The images attached are the formulas for this unit. Please make sure to show all your work using the GRASS method and using formulas from this unit (Energy and Momentum).A can of beans that has mass M is launched by a springpowered device from level ground. The can is launched at an angle of a0 above the horizontal and is in the air for time T before it returns to the ground. Air resistance can be neglected. (a) How much work was done on the can by the launching device? (b) How much work is done on the can if it is launched at the same angle a0 but stays in the air twice as long? How does your result compare to the answer to part (a)?
