Basically velocity is a vector quantity and is specified in m/s (meters/second). Speed is the distance traveled by an object where as, velocity is distance traveled by an object per unit time in a particular direction. Speed is a scalar quantity where as velocity is a vector quantity
The total displacement is 4.0 m east.
Answer:
<h2>solusion </h2><h2>
Explanation:</h2><h2>the answer in 984 </h2>
tha
Given momentum is conserved and is mv
if
mass is the same and va=2vb
then momentum is m(2vb + vb)
if collision is elastic (bounces off)
then m(2vb + vb) = m(vfa + vfb)
3vb = vfa + vfb
meaning final velocities would be different
if collision is inelastic (sticks together)
then m(2vb + vb) = (m+m)vf
meaning final velocity would be same
is this what you wanted?
Answer:
answer is (c) density is not a characteristics of vibration.
hope it is right answer for it!!
