Answer:
a) P1+P2
Explanation:
The magnitude of their combined momentum is just the addition of each momentum, because in this case of inelastic collision, the kinetic energy of the two cars are both converted to some form of energy because the velocity of both cars becomes zero, i.e., V=0, making P = mv = 0, this means the magnitude of P1 + P2 = 0.
Answer:
the value of x is 3.7 because they are arranged in a particular manner.
The first image below shows force F1 and the axes.
Answer: 
3.62 kN
Explanation: The second figure below express the parallelogram method to calculate the u component of force F1.
The <u>Parallelogram</u> <u>Method</u> is a method to determine resultant force and is applied as described in the question above.
With the three components, 
and 
and angles, it can be used the <u>Law</u> <u>of</u> <u>Sines</u>, which states:
i.e., there is a relation of proportionality between an angle and its opposite side.
For the triangle below:
u = 3.62
The magnitude of the component acting along the u-axis is 3.62kN.
Answer:
An electrical charge is created when electrons are transferred to or removed from an object. Because electrons have a negative charge, when they are added to an object, it becomes negatively charged. When electrons are removed from an object, it becomes positively charged
Answer:
0.026 meter
Explanation:
using distance time equation to determine the time for the puck to move 16.5 meters.
distance 'd' = velocity'v' x time't'
16.5 = 44 x t
t =0.375 second
Here momentum is conserved. Since both objects are initially at rest, the initial momentum is 0.
Next is to determine the puck’s momentum.
Momemtum 'p' = m x v => 0.15 x 44 = 6.6kg⋅m/s
The player momentum is -6.6kg⋅m/s .
In order to determine the player’s velocity, we'll use p=mv
-6.6 = 94v
v= -0.0702 m/s
The above negative sign represents that the player is moving in the opposite direction of the puck.
Lastly, how far does the player recoil in the time it takes the puck to reach the goal 16.5 m away?
d = v x t = 0.0702 x 0.375= 0.026 meter
