Answer:
if the stars connect to a thing, then it describes.
The answer for this change in the magnitude of momentum is the same for both because momentum is always conserved so both vehicles have the identical change.
So for determining who has the greater change in kinetic energy, momentum (P) = mv so P^2 = m^2 v^2 P^2 / 2m = 1/2 m v^2 = energy So the weightier the mass the smaller the energy change for the same momentum change so in here, the car has a greater change in kinetic energy.
Answer:
In helium
Explanation:
Since the units are the same, the value should only be considered.
The boat's initial velocity is:

While the boat's acceleration is

with a negative sign, since the boat is slowing down, so it is a deceleration. The distance traveled by the boat until it comes to a stop can be found by using the following equation:

where vf=0 is the final velocity of the boat and S is the distance covered. Re-arranging the formula, we can find S:

Answer:
a) 20 m/s
b) No
Explanation:
a)
Mr. G needs to run x= 200 m in t = 10 seconds to catch the bus.
Knowing the speed is computed as

We have

b)
The fastest human can run 12 m/s, so Mr. G won't be able to catch the bus because he needs to run faster than that
