Question

a particle of mass 1.3kg is sliding down a frictionless slope inclined at 30 to the horizontal. the acceleration of the particle down the slope is

Answer 1

Answer:

$4.9\ m/sec^2$

Explanation:

The computation of acceleration of the particle down the slope is shown below:-

data provided in the question

Particle of mass = 1.3 kg i,e sliding down

Inclined = 30 to the horizontal

based on the above information

Force is given by

$N = mg\ cos \theta$ ............ 1

and sliding force is given by

$F = mg\ sin\alpha$

$a = g(sin\ 30^{\circ})$

$= 9.8\times \frac{1}{2} m/sec^2$

= $= 4.9\ m/sec^2$

Hence, the acceleration of the particle down the slope is 4.9 m/sec^2
