distance traveled by the object thrown from the ground.

=> h = 25t-5t^2

distance travelled by the object dropped from the tower, where u = 0
200-h = 5t^2
200-(25t-5t^2) = 5t^2
t = 8 seconds

The bodies meet at the height of:
h = 25t-5t^2
h = 200 - 320 = -120
| h | = 120meters

Ahoy!

____________

Height of the tower = 200m

h = 25t - t^2

Distance travelled by dropped object = 200 - h = 5t^2

put the value of h

200 - (25t - t^2) = 5t^2

200 - 25t + t^2 = 5t^2

200 - 25t = 4t^2

t = 8 seconds

put value of t in

h = 25(8) - 5(25)^2

h = - 120m
