Answer:
B) 350 kg m/s
Explanation:
momentum or p is given by the equation p= mxv
We have the mass and velocity so we can use the equation directly
p= 72kg x 4.9 m/s
p= 352.8 kg m/s
The answer is electromagnetic Induction.

Answer:
Explanation:
Total energy is constant
E = mgh + ½mv² + Fd
At the top of the slide, all energy is potential
E = mgh + 0 + 0
At the bottom of the slide, all potential energy has converted to kinetic and work of friction.
mgh = ½mv² + W
W = mgh - ½mv²
W = 30.0[(9.81)(2.0) - ½6²]
W = 48.6 J
Answer:
The force is Centripetal force
A net force is the sum of all forces acting upon an object. A net force is capable of accelerating mass.
example: if the wheels on a bike push it forward with 5 Newtons & drag is 3 Newtons then the net force is 2 Newtons, forward.
