It’s easier to lift the wheelbarrow when the load is near the front because there isn’t any pressure near the back where the handles are.

Answer:
<h2>D) S increases because at all times Rock X falls with a greater speed than Rock Y</h2>
Explanation:
As we know that Stone X is dropped first and then after some time stone Y is dropped
Now we have
similarly for Y
now the relative acceleration of two stones while they are in air is ZERO
also we know from above equations
so the separation between two stones will keep on increasing as the speed of X is more than the speed of Y
Among drivers and front-seat passengers, seat belts reduce the risk of death by 45%, and cut the risk of serious injury by 50%. Seat belts prevent drivers and passengers from being ejected during a crash. People not wearing a seat belt are 30 times more likely to be ejected from a vehicle during a crash.

Momentum is a conserved quantity. The total momentum of the system before and after the interactions will not change. So, let's look at the momentum before the interaction.
(3.2x10^-21, 0, 0) kg*m/s and (0,0,0) kg*m/s
After the interaction
(2.6x10^-21, 1.40x10^-21, 0) kg*m/s
and the other proton has to have a momentum that when added to this momentum equal the original value. Since the y and z vectors were initially 0, all we need for the y and x vector values of the result is to negate them. The x vector value will be
3.2x10^-21 - 2.6x10^-21 = 0.6x10^21 = 6.0x10^-22. So the other proton will have a momentum of
(6.0x10^-22, -1.40x10^-21, 0) kg*m/s</span>
