Answer 1

Answer:

7.35 Joule, 3.13 m/s

Explanation:

The energy possessed by the position of the body is called potential energy of the body.

The formula for the potential energy is given by

P.E = m g h

Here, m = 1.5 kg, g = 9.8 m/s^2, h = 0.5 m

So, potential energy at B

P.E. = 1.5 x 9.8 x 0.5 = 7.35 Joule

The potential energy at B is converted into kinetic energy at point A.

$m g h = 0.5 m v^{2}$

$v = \sqrt{2gh}$

v = \sqrt{2 \times 9.8\times 0.5}

v = 3.13 m/s
