Question

A body is projected horizontally with a velocity of 2 m/s. What will be the velocity of the body after 0.5 seconds.(Take g=10 m/s²)

Answer 1

$\sf{\green{Given \rightarrow}}$

• Horizontal Velocity $\sf{v_x=2m/s}$

• Time [t] = $\sf {0.5 sec}$

$\huge{\underline{\sf{\red{Solution:\rightarrow}}}}$

At the starting point, the vertical component of velocity is zero.

After 0.5 s vertical component of velocity u is given by,

$\sf{u_y = g\times t = 10\times0.5 = 5 m/s}$

velocity of the body after 0.5s  =  

$\sf{\sqrt{5^2+2^2} \\= {5.4m/s}}$

$\underline{\boxed{\orange{\bf u_y= 5.4 m/s }}}\:\bigstar$

$\therefore\:\underline{\textsf{Velocity= \textbf{5.4m/s}}}.$
