A pebble is thrown vertically upward is it has an initial speed of U metres per second the pebble reaches a maximum height of H metres before falling vertically downwards it is known that H is directionally proportional to U^2when the bible is the phone with an initial speed of 10 m/s it reaches a maximum height of 5 m. Calculate the maximum heat reach the pebble is thrown with initial speed of 12 m/s Find the initial speed of the pebble if the maximum height reached is 16 m is an appropriate degree of accuracy.

step-by-step explanation:

step 1: solve one of the equations for one of the variables. let's solve the first equation for y:

step 2: substitute that equation into the other equation, and solve for x.

step 3: substitute x = 4 x = 4 x=4 into one of the original equations, and solve for y.
