Question

solve this
plz
let's see who is the brainest among u

Answer 1

U=0,h=h,t=?
V=u+at
V=0+10×t
V=10t
V/10=t
PLEASE MARK ME AS BRAINLIEST IF THE ANSWER IS CORRECT
Time taken to go up is equal to time taken to go down
T1=T2
V/10=V/10
Hence proved

Answer 2

If the total time of flight is T then the total distance travelled is 0. So, by second equation of motion

0= uT - 1/2 gT exp 2

T = 2u/g

Now at the highest pint, the velocity vanishes

SO, 0=u-gt, it t is time to reach the highest point

So t=u/g,so it follows that the time to come down is also u/g, so that the total is T=2u/g
