An object is dropped from a tower. if it had been thrown down at 60m/s, it would have taken half the time. What is the height of the tower? (Use gravity as 10m/s2)
Acceleration = 10m/s2
v1 = 0m/s (not sure)
v2 = 60m/s
time = t/2
The Attempt at a Solution
I tried doing the questions, but i don't understand.
The correct answer is 320m, but i don't know how to get to it.
Any help is appreciated.
