Question

A body was Thrown vertically upward and rises to a height of 10 m.velocity with which the body was thrown upward

Answer 1

Hey there,

According to 3rd law of motion----

v²-u²=2gh

Assigning values, we get----

-u²=-200

Therefore, the velocity with which it was thrown is equal to----

10√2 m/s

Answer 2

Answer:

Explanation: It’s extremely easy

H=10

We know

V^2-u^2=2as

Since body is moving upwards,acceleration due to gravity will be -10

0^2-u^2=2*-10*10

u^2=200

$U=10sqrt2$
