Answer:
B) 350 kg m/s
Explanation:
momentum or p is given by the equation p= mxv
We have the mass and velocity so we can use the equation directly
p= 72kg x 4.9 m/s
p= 352.8 kg m/s
<u>Answer:</u>
<em>The moon doesn’t change shape on its own.</em>
<u>Explanation:</u>
Shapes of moon that we observe is based on the different perspectives of view from the earth and position of moon with respect to the sun. The changes arise due to the rotation of earth on its own axis as well as the revolution of moon on its orbit. The moon doesn’t have any light of its own.
It just reflects off the light from the sun. Due to tidal locking phenomenon one face of the moon permanently faces the sun. Because of the changes in position of moon with respect to the sun the moon is lighted up variably giving rise to various phases like new moon, full moon, crescent etc.

Answer:
Magnitude F(t)=26.6 N
Direction: -x
Explanation:
Given data
Spring constant K=4.77 N/m
Mass m=1.89 kg
Displace A=5.56m
Time t=3.96s
To find
Magnitude of force F
Solution
The angular frequency is given as
Force on object is
Substitute given values
So
So
Magnitude F(t)=26.6 N
Direction: -x
Answer:
velocity because it says you are going 3 miles north and velocity is something going a speed in a certian direction
