WebLet the height from the bottom of the tower to the point of intersection be h 2. Let the time taken for the intersection of the two balls be t. Step 2: Calculate the height h 1 According to Newton's second equation of motion we get, S = u t + 1 2 a t 2 ⇒ h 1 = 0 + 1 2 × 10 × t 2 ⇒ h 1 = 5 t 2 1 Step 3: Calculate the height h 2 Weba)distance between pole and tower=50cm in triangle amc, tan 30= am/mc = am/bd therefore, am = 50/sqrt (3) or 28.87 (approx.) b) height of the pole = cd=bm =50-28.87 = …
