A pack of bricks of mass 100kg is hoisted up the
side of a house. Find the force in the lifting rope
when the bricks are lifted with an accelerntion of
0.25m/s?.
To find the force in the lifting rope, we need to use Newton's second law of motion, which states that force is equal to mass multiplied by acceleration (F = ma).
Given:
Mass of the bricks (m) = 100 kg
Acceleration (a) = 0.25 m/s^2
Using the given values in the formula:
Force (F) = mass (m) x acceleration (a)
F = 100 kg x 0.25 m/s^2
F = 25 N
Therefore, the force in the lifting rope when the bricks are lifted with an acceleration of 0.25 m/s^2 is 25 Newtons.
To find the force in the lifting rope, we can use Newton's second law of motion, which states that force (F) is equal to mass (m) multiplied by acceleration (a): F = m * a.
In this case, the mass of the brick is given as 100 kg and the acceleration is 0.25 m/s². Plugging those values into the formula, we get:
F = 100 kg * 0.25 m/s²
F = 25 N
Therefore, the force in the lifting rope when the bricks are lifted with an acceleration of 0.25 m/s² is 25 Newtons.
