Inclined plane

On the inclined plane with an inclination angle of 30°, we will put the body (fixed point) with mass 9 kg. Determine the acceleration of the body motion on an inclined plane.

Correct answer:

a =  4.91 m/s2

Step-by-step explanation:

m=9 kg g=9.81 m/s2 α=30 °  G=m g=9 9.81=8829100=88.29 N Fn=G cosα°=G cos30° =88.29 cos30° =88.29 0.866025=76.46138 N Fp=G sinα°=G sin30° =88.29 sin30° =88.29 0.5=44.145 N  Fp=ma  a=Fp/m=44.145/9=4.91 m/s2
