Question

A force of 72 dyne is inclined to the horizontal at an angle of 60°. Find the acceleration in a mass of 9 g, which moves in a horizontal direction.

Answer 1

if we divide then the answer will occour

Answer 2

Answer:

$4 cm/s^2$ or $0.04 m/s^2$

Explanation:

Horizontal component = Fcos60*

F = 72 dyne (CGS)

Horizontal component = 72dyne *  (1/2) = 36 dyne.

Mass = 9g.

Acceleration = 36dyne/9g = $4 cm/s^2$

Or: $0.04 m/s^2$
