If v = 5.00 meters/second and makes an angle of 60° with the negative direction of the y–axis, calculate the possible values of vx. A. –4.33 meters/second and +4.33 meters/second B. 2.50 meters/second C. –2.50 meters/second and +2.50 meters/second D. 4.33 meters/second
Answers
Answer ⇒ Vx = + 4.33 m/s.
Option (b).
Explanation ⇒
Refer to the attachment for the question.
v = 5m/s.
Vx = VSin60
Vx = 5 × √3/2
∴ Vx = + 4.33 m/s.
Hence, the component of the velocity that we can easily figure out from the figure is + 4.33 m/s.
Hence, Option (b). is the correct choice.
Hope it helps.
answer
0.004 kg m/s
explanation:
given : mass= 200g = 0.2 kg
velocity = 2cm/s = 0.02 m/s
momentum= mass x velocity
= 0.2 kg x 0.02 m/s
= 0.002 kg m/schanges in mass
an object's mass and momentum are directly related; as mass increases, momentum will have a corresponding increase, assuming a constant velocity. thus, an object with twice the mass of another object -- moving at the same speed and in the same direction -- will have twice the momentum.
