Question

The projectile is projected horizantally with 10m/s after 2sec of its journey the horizental and vertical compenent of its velocity will be......???

10m/s , 10m/s
10m/s , 19.6m/s
19.6m/s , 10m/s​ ​

Answer 1

The horizontal component of velocity will be 10m/s as no acceleration is experienced by the projectile in the horizontal direction.

The vertical component of velocity :

By newton's law of motion

v=u+at

v=10-20    (as a=-10m/s^2 and t=2sec)

∴v=-10m/s

Therefore, the vertical component of velocity will be 10m/s in the downward direction.

Answer 2

Answer:

this is the vertical component and the horizontal component will be same as it is 10
