With what initial velocity must an object be thrown upwards so that it will reach a maximum height of 800 feet? Assume the that
Flauer [41]

Answer:

Option b is right.

Step-by-step explanation:

When an object is thrown upwards, the acceleration acting is acceleration due to gravity in a negative manner.

a = -32 ft/sec square

Initial velocity let it be u

Final velocity when it reaches maximum height is 0

Use the formula connecting, u, v, a and s

v^2=u^2+2as\\0 = u^2-2(32)(800)\\u = \sqrt{64(800)} \\u = 160*0.707\\= 226.27ft/sec

Hence we find that initial velocity is 226 ft/sec

Option b is right.
