an object thrown vertically up from ground passes the height 10 metre twice in the time interval of 10 sec the time of flight is

```							Let the height of the highest point that the object reached be S metersThe object has climbed the height of (S-10) m in 10s/2 = 5 seconds and  it descended (S-10) m in the same time =  5secwe use s = ut + 1/2 a t²S – 10 = 0 * 5 + 1/2 * 9.8  * 5²S = 132.5 metersTime duration for the object to travel vertically 132.5 meters132.5 = 0 t + 1/2 * 9.8 * t²t² = 27.041      t = 5.196 secTotal time of flight = 10.392 second

```							Object passes through 10m height twice in 10sso object reaches highest peak in 5s (as it will take equal time interval for going up and coming down) let velocity at highest point be Vapplying equation of motion V=U+athere V is final velocityU is initial velocitya is acceleration due to gravity(here it is negative acceleration as acceleration due to gravity acts in opposite direction, so a=-g=(-9.8m/s²)here V=0, a=-9.8m/s², t=5s0=U-9.8*5U=49m/sat 5m height V=49m/s, a=-9.8m/s²,s=5mV²=U² + 2as49²=U² - 2*9.8*10U²=2597U=51 m/sAgain V=U+a*tso final velocity V=0, initial velocity U=51m/s, a=-9.8m/s², t we need to find0=51-9.8*tt=51/9.8=5.2s (it is the time of going up)So total time period is 2*5.2=10.4s
