Answer:
The force the skater exerts is 50 N
Direction: towards wall
Explanation:
The impulse is equal to:
The average force is:
Where
vf = final speed = -1 m/s
vi = initial speed = 0
m = mass = 40 kg
Δt = time interval = 0.8 s
Replacing:
(force applied by the wall)
The force the skater exerts is
Fsk = -Fave = -(-50) = 50 N
Direction: towards wall
Answer:
Third Option
Explanation:
If we have a vector A = ax + by we know that by definition
cA = cax + cby
Where c is a constant.
In this case we have two vectors
You may notice that vector B has an opposite direction to vector A.
You may also notice that | Ax | is the double of | Bx | and | Ay | is double of |By |
That is to say
So the equation that relates to vectors A and B is:
.
You can verify this relationship by performing the operation
