Question

A ball is thrown vertically upwards .It rises to a height of 125 m and comes back to the thrower

Answer 1

Answer:

The equation is given as v

2

−u

2

=2as.

where,

v = final velocity,

u = initial velocity,

a = acceleration due to gravity, 10m/s

2

,

s = h = height traveled.

Therefore, we can find u with above info. In this case, v = 0 at the top of the path.

0−u

2

=2×10×5=10m/s.

Hence, the initial velocity of the ball was 10 m/s.

Answer 2

$\LARGE{\color{t}{\textsf{\textbf {\underline{ Anѕwєr : }}}}}$

so what uh wanna know?

the distance that ball's covers?

then,

• distance = 35m +35m

= 70m

and

• displacement= 0
