Peer mediation is problem solving by youth with youth. It is a process by which two or more students involved in a dispute meet in a private, safe and confidential setting to work out problems with the assistance of a trained student mediator.
Answer:
5.8 m/s
Explanation:
Let v = velocity of bike relative to Betty = -12.0 m/s (since the bike is moving away from betty).
u = velocity of ball relative to bike = + 17.8 m/s
and V = velocity of ball relative to Betty.
So, by Galilean relativity,
V = v + u
V = -12.0 m/s + 17.8 m/s
V = 5.8 m/s
So, the velocity of the ball as measured by Betty is 5.8 m/s
The substances that will be good conductors of electricity are NaCI(s) and NaCi(l)
The initial velocity of the hockey puck is obtained as 22 m/s.
<h3>What is the frictional force?</h3>
The frictional force of the hockey puck is the force that causes it to stop. Now;
Ff = μmg
Ff = 0. 51 * 0.16 Kg * 9.8 m/s^2
Ff = 0.8 N
Now;
F = mv^2/2x
Where;
m = mass
v = velocity
x = distance
v =√ 2xF/m
v = √ 2 * 47.7 * 0.8 / 0.16
v = 22 m/s

Answer:(a) The answer is (2)(a factor of 1). The stopping distance does not change. That is because both the kinetic energy and the friction force double.
(b) 4) 0.25
