A gun fires a bullet. The barrel of the gun is inclined at an angle of `45^@` with horizontal. When the bullet leaves the barrel it will be travelling at an angle greater than `45^@` with the horizontal. Is this statement true or false?

Text Solution

Verified by Experts


At `45^@` means horizontal and vertical components are same (letu).

In absolute velocity, since horizontal component of velocity has been decreased `(=u-v)`.Therefore, `thetagt45^@`
