Answer the physics question Pls.... ​

Answer»

Hii MATE ❤Explanation:Assume, the FINAL velocity with which the ball will strike the ground be ‘v’and time it takes to strike the ground be ‘t;Initial Velocity of ball, u =0Distance or HEIGHT of fall, s =20 mDownward acceleration, a =10 m s-2As we know, 2as =v2-u2v2 = 2as+ u2= 2 x 10 x 20 + 0= 400∴  Final velocity of ball, v = 20 ms-1t = (v-u)/a∴Time TAKEN by the ball to strike = (20-0)/10= 20/10I hope it's help you ❤❤= 2 seconds
