Acceleration occurs whenever the forces on an object are unbalanced.
It's the group of forces on the object that's either balanced or unbalanced.
There's no such thing as "an unbalanced force".
Answer:
A stop watch
A speedometer
Explanation:
Acceleration is the rate of change of velocity of an object with respect to time.
The speedometer can indicate the different speeds, the starting and the final velocity. Then with the stop watch can be used to capture the change in time.
However, acceleration can be measured directly using an accelerometer.
Answer:
Their velocity is 0m/s because the first box was only 10 kg and the second box was double the weight
Answer:
0.011 N-m
Explanation:
Given that
The mass of a solid cylinder, m = 30 kg
The radius of the cylinder, r = 0.18 m
The acceleration of the cylinder,
It rotates about an axis through its center. We need to find the torque acting on the cylinder. The formula for the torque is given by :
Where
I is the moment of inertia of the cylinder,
For cylinder,
So,
So, the required torque on the cylinder is 0.011 N-m.
