A ball is dropped off the side of a bridge. After 1.55 s, how far has it fallen?

(Unit = m)

Remember: Falling = -V

Lost height = -Ay

a = -9.80 m/s2 Be careful with minus signs!!!

If a tank filled with water contains a block and the height of the water above point a within the block is 0.8 meter, what is the pressure at point a?

One form of energy can be another type of energy. a. created to form b. transformed into c. destroyed and then created to form

(a) assume the equation x = at^3 + bt describes the motion of a particular object, with x having the dimension of length and t having the dimension of time. determine the dimensions of the constants a and b. (use the following as necessary: l and t, where l is the unit of length and t is the unit of time.) (b) determine the dimensions of the derivative dx/dt = 3at^2 + b. (use the following as necessary: l and t, where l is the unit of length and t is the unit of time.)
