A ball is rolled off the edge of a horizontal table at a speed of $4\, m/s$. It hits the ground after $0.4\, sec$. Which statement given below is true?

A

It hits the ground at a horizontal distance $1.6 \,m$ from the edge of the table

B

The speed with which it hits the ground is $4.0\, m/s$

C

Height of the table is $0.9 \,m$

D

It hits the ground at an angle of $60^o$ to the horizontal

Solution

$\therefore R = u.T = 4 \times 0.4 = 1.6\, m$
