Answer:
5.95m/s to 2 decimal places
Explanation:
In physics speed is measured in metres per second so convert 8mins to seconds
8x60=420 seconds
The formula needed:
Speed (m/s)= Distance (m)/Time (s)
2500/420=5.95m/s
Newton's first law of motion states that an object at rest stays at rest unless acted upon by a force while an object at motion stays in motion unless acted upon by an opposite force. Therefore, the ball in motion will stay at motion considering there is no friction force in the field, answer is A. If the field has friction force against the ball then it will slow down and stop eventually, answer is B.
It’s called earth’s rotation
Answer:
The acceleration of the crate is .
Explanation:
Given that,
Force, F = 750 N
Mass of the crate, m = 250 kg
The coefficient of friction is 0.12.
We need to find the acceleration of the crate. The net force acting on the crate is given by :
f is frictional force,
So, the acceleration of the crate is . Hence, this is the required solution.
