Answer:
The velocities of each ball are
Explanation:
Using the conservation of momentum to find the velocity of each balls after the collision
Here have one equation but have two variable don't know so
Now have two equations and two variables so solving using
Answer:
<h2>
<u>76.36m/s</u></h2>
Explanation:
Step one:
given data
let the mass of the rider be m,=110kg
let the velocity be v=?
let the mass of the car be M,=110kg
let velocity of the car V=6m/s
Step two:
the momentum of an object is given by the expression
P=mv
<em />
Step two:
<em>since the two the bicycle rider must have the same momentum as the car,</em>
<em>then we need to equate their momentum</em>
mv=MV
110*v=1400*6
110v=8400
divide both sides by 110 to find v
v=8400/110
v=76.36m/s
<u>The rider is expected to have a speed of 76.36m/s</u>
