The state of matter that has particles that slide by one another is liquid because liquid is very slippery.
Answer: 20 m/s
Explanation: To solve this problem we have to consider the expression of the kinetic energy given by:
Ekinetic=(1/2)*(m*v^2)
then E=0.5*30Kg*(20 m/s)^2=15*400=6000J
Answer:


Explanation:
From the question we are told that
Initial velocity of 60 m/s
Wind speed 
Generally Resolving vector mathematically

Generally the equation Pythagoras theorem is given mathematically by



Therefore Resultant velocity (m/s)

b)Resultant direction
Generally the equation for solving Resultant direction

Therefore

change in momentum/3=200
change in momentum =3*200 kg m/s
