Answer:

Step-by-step 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
............ 1
and sliding force is given by



=

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