The distance traveled by an object can be modeled by the equation d = ut + 0.5at2 where d = distance, u = initial velocity, t = time, and a = acceleration. solve this formula for a. show all steps in your work. plz someone > ~< .

What is tan(61)? а. 1.80 b. 0.49 c. 0.61 d. 0.87

Apebble is thrown into a calm lake, ripples are formed from the center and move outward. the water particles in the lake travel in a circular pattern that moves up and down on the surface of a lake, and the energy travels a) diagonally. b) downward. c) horizontally. d) upward.

If the force applied to an object remains constant, is more power needed for the object to move faster ? explain
