Answer:
20 m/s
Explanation:
The acceleration of an object determines the increase in velocity per second.
In this case the acceleration is 20m/s^2.
That is, the increase is 20m/s each second.
I hope this is useful for you

Answer:
Torque = 0.25Nm
Explanation:
To calculate the magnitude of torque, first we must calculate the lever arm. The lever arm is perpendicular distance from the axis of rotation to the line of the action of the force.
Lever arm = r sin theta
Where r = 4.9cm= 0.049m
Theta = 30°
Lever arm = 0.049 sin30° = 0.245m
Magnitude of torque = rfsintheta
f = 1.0T
Magnitude of torque= 0.245×1.0 = 0.245Nm
To 2 significant figure=0.25Nm
