**Given,**

**Let the heights be h1 and h2 **

**V1 = 0 m/s**

**V2 = 25 m/s**

**Acceleration = 10 m/s²**

**Now,**

**S = ut+1/2*at²**

**S = ½*10*t²**

**S = 5t²**

**Again,**

**S = ut+1/2at²**

**S = 25*t+1/2-10*t²**

**S = 25t-5t²**

**Now,**

**H1+H2 = 100**

**Therefore,**

**-5t² + 25t-5t² = 100**

**25t = 100 **

**T = 4 sec**

**Therefore time = 4 sec and **

**H1 = 5t² = 5*16 = 80 m**

**And H2 = 25t-5t² = 25*4-5*16 = 100-80 = 20m**

**I hope it helps…… **
