Answer:
Explanation:
We need to supply 5 Nm to the bolt.
If we have a force of 25 N in the direction (2*i - 3*j), the torque is related to the length of the wrench.
T = F * d
d = T / F
d = 5 / 25 = 0.2 m
Assuming the wrench is perpendicular to the force.
The vector of the force is:
This is a countr-clockwise direction. If the bolt is right handed (most are) we are tightening it.
Given:
Time taken for the travel: 40 mins=2400 secs
Velocity: 1.2m/s
Speed and velocity have the same magnitude. Speed is a scalar where as velocity is a vector quantity.
Distance traveled= speed x time.
Distance traveled: 1.2 x 2400=2880m
