Dominador, who is standing on the edge of an 80-m tall cliff facing the sea, kicks a ball horizontally at a speed of 13.01 m/s. How far from the base of the cliff will the ball hit the sea water?

Let  be the initial vertical position of the ball, with positive position in the upward direction. The vertical displacement of the ball from the edge of the cliff to the seawater is:

Supply all missing information with the correct numerical values. Do not include the units. Round off all answers to two decimal places. Do not forget the negative sign (-) if needed. Mr. One is pushing a cart with a force of F1 = 15.00 N due north. Mr. Two is pushing the same cart with a force of F2 = 25.00 N due northeast. Mr. Three is pushing the cart a force F3 so that the cart is in equilibrium. Find force F3 so that F + F2+ F3 = 0. First, we calculate the vector sum F1 + F2 by component method. The x-component of F1 is and the y-component is The x-component of F2 is and the y-component is Adding the components, we can express the resultant vector in unit vector component form: Fi+F2 = ↑ + Since we want to find F, +F2+ = 0, it follows that F3 = - (F1 + F). Thus, F3= The magnitude of F3 is F3 = N.
