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
ft/sec
Hence we find that initial velocity is 226 ft/sec
Option b is right.
