Your body loses heat to the water faster than it loses heat to the air. Water has a higher heat capacity, so it is better at extracting heat than air is.
Answer:
The total displacement of the car is 2 meters south
Explanation:
As the car went south 10m, and then went back over it initial path for 8 meters, the actual distance registered in the car's odometer will be 18 m, but as far as vector displacement in its final position, this will be 2 meters south (10m -8m=2m).
Notice that the displacement vector is defined as the final position minus the initial position, which gives a distance of 2 from the origin, in the suoth direction.meters
By conservation of momentum, the initial recoil speed of the
rifle is:
u = 904kg * 0.0106 kg / 3.53 kg = 2.7146 m/s
The final recoil speed v is zero in a distance of d = 0.0346 m
So the rifle's acceleration is a = (0 - u^2) / 2*d = -2.7146^2 / 2*.0323
m/s^2
a = -114.07m/s^2
