Answer 1

★ A ball is thrown up with a speed of 0.5 m/s

so,

u ( initial velocity ) = 0.5 m/s

v ( final velocity ) = 0

a = -g = -10 m/s²

Using Equations of motion ,

v² - u² = 2as

0 - (0.5)² = 2 × (-10) × s

-0.25 = -20 s

s = 0.0125m

Now ,

v = u + at

0 = 0.5 + (-10)t

10t = 0.5

t = 0.05 sec
