Question

A body is moving with velocity 30 metre per second towards east after 10 seconds it its velocity becomes 40 metre per second towards north the average velocity of the body is
A5 metre per second square
B1 m per second square
C7 metre per second square
DRoot 7 metre per second square

Answer 1

the answer should be 5 metre per second square this can be done by finding the resultant of two velocity that is in the east and the west direction we find that the magnitude of resultant come out to be 50 M per second square now we know that the average acceleration is the resultant acceleration divided by X 50 divided by 10 is equal to 5

Answer 2

7 m/s is the right answer the Average velocity of the body is the answer C
