A ball of mass 50g tied to the end of a 50cm inextensible string is whirled around in a vertical circle. find the tension in the string when the ball is at the top of the circle. take g = 10m/s
To calculate the acceleration of the elevator, we can use Newton's second law of motion, which states that the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass. The formula to calculate acceleration is:
acceleration (a) = net force (F) / mass (m)
Given:
Net force (F) = 12,104 N
Mass (m) = 20,000 kg
Acceleration due to gravity (g) = 9.8 m/s^2
To find the acceleration, we'll substitute the given values into the formula:
a = F / m
a = 12,104 N / 20,000 kg
Now, let's calculate the acceleration:
a = 0.6052 m/s^2
Therefore, the acceleration of the elevator is 0.6052 m/s^2.
