Question

a mass of 2 kg is thrown vertically upward with a velocity of 20m/s How much height will it go how long will it take to reach the same level​

Answer 1

Explanation:

h= u^2/2g so h=20*20/20 =20

Answer 2

Explanation:

Given-:

Initial velocity(u) = 20m/s

Acceleration due to gravity= 10m/s²

Mass of body= 2kg

To find-:

(Maximum Height)=?

Time to reach the max.Height=?

Solution-:

Maximum Height= u²/2g

Maximum Height= 20²/20

Maximum Height= 20m✓✓✓✓

Time to reach max. height= u/g

Time to reach max. height= 20/10

Time to reach max. height= 2sec
