Answer:
the maximum height reached by the marble is 11.84 m.
Explanation:
Given;
mass of the marble, m = 0.02 kg
extension of the string, x = 0.08 m
force applied to the string, F = 58 N
Apply the principle of conservation of energy;
elastic potential energy = gravitational potential energy
¹/₂fx = mgh
Therefore, the maximum height reached by the marble is 11.84 m.
For a free-falling or an object thrown up, the only force acting upon it is the gravitational force. This gravitation pulls the object constantly towards the center of the Earth. As a result, during the whole motion, the force induces an acceleration with a constant value of 9.81 m/s². Therefore, the acceleration doesn't change anywhere and anytime in the whole duration of motion.
Explanation:
First convert the speed into m/s and time into seconds
Answer:
It moves 1.71m to the left.
Explanation:
The intial position of the center of mass is:
The final position of the center of mass is:
The displacement between these positions is:
Δr = 5.34m - 7.05m = -1.71m
This means it moves 1.71m to the negative x-axis
