Question

One second after projection, the horizontal and vertical velocities of a projectile are found to be equal and after one more second, the motion of the projectile is along the horizontal. The horizontal range of the projectile is \[ (g=10~\text{m s}^{-2}) \]

• A. \(10~\text{m}\)
• B. \(20~\text{m}\)
• C. \(30~\text{m}\)
• D. \(40~\text{m}\)

Hint:

Projectile formulas: \[ \boxed{ T=\frac{2u_y}{g}, \qquad R=u_xT } \] Horizontal motion has \[ \boxed{v_y=0.} \]

Answer 1

The Correct Option is D
