Step-by-step explanation:acc. to newtons equations

v = u + gt ( acceleration = acc. due to garvity )

v = 0 + 10 x 1

v = 10 m / s

the ball will reach the ground at a speed of

10 m/s

acc. to second equation

v^2 = u^2 + 2gs

100 = 0 + 2 x 10 x s

100 /20 = s

s = 5 m

Step-by-step explanation:h=1/2gt²

h=1/2(10)(2)²

h=20m

h=vt

20=2v

v=10m/s OK friend
