Question

. A ball falls off a table and reaches
the ground in 1 s. Assuming g = 10
m/s?, calculate its speed on reaching
the ground and the height of the
table.

5m

$\huge{\underline{\tt{\blue{Explanation-}}}}$

Initial velocity u=0 Let final velocity is v and height is h.

Using v=u+at

$\implies v=0-10\times 1 = -10 m/s$

$Using \ s=ut+ \dfrac{1}{2} at^2$

$\implies -h = 0\times 1 - \dfrac{1}{2}\times 10 \times 1^2$

$\implies h = 5m$
