Hi there!
Recall:
Impulse = Change in momentum
I = Δp = mΔv = m(vf - vi)
Let the direction TOWARDS the floor be POSITIVE, and AWAY be NEGATIVE.
Plug in the givan values:
Δp = 1.5(-10 - 12) = -33 Ns
**OR, the magnitude: |-33| = 33 Ns
Dont get ecited if u get a notification I needed......
points!
Answer:
0.064 m
Explanation:
When a spring is stretched/compressed, the force exerted in the spring is related to the elongation of the spring by the equation:

where:
F is the force applied
k is the spring constant
x is the stretching/compression of the spring
In this problem, we have:
is the force applied by the kid on the spring
k = 128 N/m is the spring constant
Solving for x, we find how far the spring stretches:
