Answer:
a) The speed of the ball is 2.47 m/s (in -x direction)
b) The speed of the block, both just after the collision is 1.236 m/s (in +x direction)
Explanation:
Please look at the solution in the attached Word file.
The answer is B, the average kinetic energy increases.
Kinetic energy is energy of motion, So by making a liquid then a gas, you can see the molecules are more mobile meaning an increas in Kinetic energy :)

Answer:
v = 12.3 m / s
Explanation:
This is an exercise in kinetics in one dimension
v² = v₀² + 2 a x
In this exercise they tell us that the initial velocity is (v₀ = 13 m / s), the acceleration is a = -0.95 m / s2 and the distance x = 9.2 m
we substitute
v = √ (13 2 - 2 0.95 9.2)
v = 12.3 m / s
note that as the acceleration is negative the vehicle is stopping
The intensity of an electromagnetic wave increases with the field strength.
Newton's 2nd Law of Motion: Force = (mass) · (acceleration)
Do I need to go any further ?
I get 575.25 Newtons .
Oh ! Look at that ! Right there at the top, it says "Using Newton's Second Law". This might have suggested to you that maybe you could solve the problem by using Newton's Second Law.
