Answer:
a) 256 ft
b) 32 ft/s
c) -32 ft/s
Explanation:
t = Time taken
u = Initial velocity
v = Final velocity
s = Displacement
a = Acceleration due to gravity = 32 ft/s²
Maximum height = 256 ft
When s = 240 ft
Speed of the ball at 240 ft is 32 ft/s while going up
Now this will be the velocity of the ball when it reaches 240 ft, which will be considered as the initial velocity
Now, initial velocity will be considered as zero
Speed of the ball at 240 ft is -32 ft/s while going down
