A particle of mass 1.3 kg is sliding down a frictionless slope inclined at 30^o to the horizontal. The acceleration of the particle down the slope is A) 1.3 m/s². B) 9.8 m/s². C) 0.5 m/s². D) 8.5 m/s². E) 4.9 m/s².

Question

Quizplus · Accepted Answer

The acceleration down the slope can be found using the formula a = g*sin(theta), where g is the acceleration due to gravity (9.8 m/s^2) and theta is the angle of the slope. Plugging in the given values, we get:

a = 9.8*sin(30)
a = 4.9 m/s^2

Therefore, the best choice is E: 4.9 m/s^2.
