Answer
given,
radius of earth,r = 1.5 x 10¹¹ m
Time,T = 365 days
= 365 x 24 x 3600 s
earth velocity,
v = 3 x 10⁴ m/s
centripetal acceleration of the earth
a = 6 x 10⁻³ m/s²

A manufacturer of printed circuit boards has a design
capacity of 1,000 boards per day. the effective capacity, however, is 700
boards per day. recently the production facility has been producing 950 boards
per day. The design capacity utilization is (950/100) *100 = 95 %
Answer:
-7.5 kg m/s
Explanation:
Initial momentum (p1) = 4.5 kg m/s
final momentum (p2) = -3.5 kg m/s
We have to find out the change in momentum , As linear momentum is a vector quantity. So, we have to use the vector form to solve the momentum change . Means we have to take the sign of momentum also.
Change in momentum = Final momentum - initial momentum
So,
Change in momentum = p2 - p1
Insert values from question,
Change in momentum = -3.5 kg m/s - 4 kg m/s
So, change in momentum = -7.5 kg m/s
