Action: ball hits your hand and is caught. Reaction: kinetic energy is transferred to your body and the ball's velocity is reset to the at rest position.

A ball with a momentum of 16 kg.M/s strikes a ball at rest. What is the total momentum of both the balls after the collision.
melomori [17]

Answer:

Total momentum = 16 Kgm/s

Explanation:

Let the momentum of the two balls be A and B respectively.

Momentum A = 16 kgm/s

Momentum B = 0 kgm/s (since the ball is at rest).

Total momentum = A + B

Total momentum = 16 + 0

Total momentum = 16 Kgm/s

Momentum can be defined as the multiplication (product) of the mass possessed by an object and its velocity. Momentum is considered to be a vector quantity because it has both magnitude and direction.

Mathematically, momentum is given by the formula;

Momentum = mass * velocity

What is the length of the x-component of the vector shown below?
ollegr [7]

Answer:

Option B. 8.1

Explanation:

From the question given above, the following data were obtained:

Angle θ = 71°

Hypothenus = 25

Adjacent = x

Thus, we can obtain the x component of the vector by using the cosine ratio as illustrated below:

Cos θ = Adjacent /Hypothenus

Cos 71 = x/25

Cross multiply

x = 25 × Cos 71

x = 25 × 0.3256

x = 8.1

Therefore, the x component of the vector is 8.1

Can You help me understand how to calculate net force please
VladimirAG [237]
To start off.. add any and all the vectors acting on the same axis (x and y), making sure to pay attention to the director of the vectors. you are often able to ignore many of the forces that cancel each other out. make sure to focus on the forces that are actualy involved in how the object will move. Then you calculate the net force acting on the object in the situation
Since nothing is happening along the y-axis, you can ignore the Fg (300N)and FN (20N) forces.

FNET = Fa + Ff

= 80N + -70N

FNET = 10N

you have to make the friction a negative force
because it is pointing in the direction opposite to the applied force.

When you want to calculate the acceleration of an object, always use the net force acting on it.

you aren’t subtracting the two forces.
Instead, it’s up to you to remember that if one of the forces is pointing in one direction (like to the right), and the other force is pointing in the other direction (like to the left), you will need to make one positive and the other negative.

i don’t really know how to explain this super well. i hope this helps!!
