Answer:
v = 66.4 m/s
Explanation:
As we know that plane is moving initially at speed of
now we have
now in Y direction we can use kinematics
since there is no acceleration in x direction so here in x direction velocity remains the same
so we will have
Answer:
The force required to pull a wagon if 84 J of work are exerted to pull a wagon 7m is 12 Joules.
HOW TO CALCULATE WORK DONE:
Work done can be calculated by multiplying the force applied on an object by the distance traveled. That is;
Work done = Force × distance
Force = Work done ÷ distance
According to this question, the work done is 84J and the wagon was pulled to a distance of 7 metres. The force is calculated as follows:
Force = 84J ÷ 7m
Force = 12N.
Therefore, the force required to pull a wagon if 84 J of work are exerted to pull a wagon 7m is 12 Joules.
It would be the lithosphere
