Answer:
Acceleration up the ramp = -2.745 m/
Explanation:
Given
box is pulled at angle Θ =
Force applied F = 185N
coefficient of friction, μ = 0.27
mass of the box m = 35 kg
We know that,
acceleration due to gravity g = 9.8 m/
horizontal component = F cosΘ = 185 * cos
=167.67
vertical component = F sinΘ =185*sin
= 78.18
Another vertical component is due to gravity , force in given by
= mg
= 35 x 9.8
= 343.35 N
Normal force =
-
= 343.35 - 78.18
= 265.17 N
Frictional force =
* μ
= 265.17 * 0.27
= 71.596 N
To find acceleration, we know that,
force = mass x acceleration
acceleration =
Here force is the summation of frictional force and horizontal component of the applied force. These force act in opposite directions.
force = -
= 71.596 - 167.67
= -96.074
acceleration =
= -2.745 m/
