Answer:
Assuming that you meant the final velocity of 50 m/s was reached in 10 s, the answer would be 5 m/s^2.
Explanation:
So we update that with the values that we have.
then simplify that using algebra to solve for a and we get 5 m/s^2
Which of the following are not conditions for producing work?
2 answers:
Answer:
A and C
Explanation:
We know that
Work done,W=Fd
Where F=Applied force
d=Displacement of object
Momentum, p= mv
It is not necessary that momentum must be greater than force .If momentum is less than force then the work can be produced because work depend upon displacement and applied force.
If the value of theta is not equal to zero the work can be produced if theta is equal to 30 ,45 or 60 degree.
Therefore, it is not necessary that atleast part of the applies force must act along the same line object moves.
If force is greater than weight then, the work can be produced .
If force is less than the weight then, the work cannot be produced .
Hence, the force must be very large.
