A soccer ball is kicked vertically from the ground with an initial velocity of 96 ft/sec.

write a quadratic function, h(t), that shows the height, in feet, of the soccer ball, t seconds after it was kicked.

(a) calculate the molarity of a solution that contains 0.0345 mol nh4cl in 400 ml of solution. (b) how many moles of hno3 are present in 35.0 ml of a 2.20 m solution of nitric acid? (c) how many milliliters of 1.50 m koh solution are needed to supply 0.125 mil of koh ?

This is different from the first one can someone me
