Watch them and make sure they dont gop out in the street because they will die
Distance and displacement are hardly ever equal.
Remember that 'displacement' is the straight-line distance between
the start-point and the end-point, regardless of what path you followed
on the way.
So they're equal ONLY when the trip from start to finish was completely
in a straight line.
Answer:
Ping Pong ball move at velocity 160.4 m/s
Explanation:
given data
mass m1 = 7 kg
velocity v1 = 3 m/s
mas m2 = 2.45 g = 2.45 × kg
same kinetic energy
to find out
How fast Ping Pong ball move (v2)
solution
we know same KE
so
...........1
so v2 will be
v2 = .............2
put here value in equation 2 we get v2
v2 =
v2 = 160.4
so Ping Pong ball move at velocity 160.4 m/s
