Hey there!
Seems like you're looking for the size and direction to the final velocity of the two cars. To find it, you must solve it like this.
0.4 kg(3 m/s) + 0.8kg(–2 m/s) = 1.2 kg m/s -1.6 kg m/s = –0.4 kg m/s
–0.4 kg m/s = 1.2 kg(v) = (–0.4 kg m/s)/(1.2 kg) = v = –0.33 m/s
So, the cars are traveling at -0.33 m/s in the direction of the second car.
Hope this helps

Answer:
Explanation:
Notice that nothing but the mass and height are given, and the mass is not really necessary. It will cancel when we do the problem.
So the potential energy at the top equals the Kinetic energy at the bottom.
PE_top = Ke_bottom
mgh = 1/2 m v^2 Divide by m
mgh/m =1/2 mv^2/m
gh = 1/2 v^2 Multiply both sides by 2
2gh = v^2

g = 9.81
h = 1.5
Solution
2*9.81 * 1.5 = v^2
29.43 = v^2
v = sqrt(29.43)
v = 5.425
To find the momentum of an object, we multiply its mass and velocity together. Using this method, a bowling ball with a mass of 7.10 kg moving at a velocity of 5 m/s has a momentum of 35.5 kg * m/s.
The subject of your question involves calculating momentum. It's based on the principles of Physics. Momentum is defined as the product of an object's mass and its velocity. It's crucial in understanding motion, specifically related to the concepts of force and mass.
To calculate the momentum of the bowling ball, the formula p = mv is used where 'p' represents momentum, 'm' stands for mass and 'v' is the velocity. In this case, the mass of the bowling ball is 7.10 kg and its velocity is 5 m/s.
So, multiplying these together (7.10 kg x 5 m/s), the resulting momentum of the bowling ball is 35.5 kg * m/s.

An ideal ammeter has zero resistance to avoid altering the current it measures, while an ideal voltmeter has infinite resistance to prevent drawing current from the device it's measuring the voltage of.
The resistance of an ideal ammeter is zero ohms. This ensures that it doesn't interfere with the current it is measuring. An ammeter is connected in series with the circuit, and if the resistance were greater than zero, it would decrease the amount of current circulating in the circuit.
On the other hand, an ideal voltmeter has infinite resistance. This happens because a voltmeter is connected in parallel with a device to measure its voltage, and to avoid drawing current from the device, an ideal voltmeter should have infinite resistance.

b. High Renaissance
c. Late Renaissance
Answer:
The correct answer is option B, High Renaissance
Explanation:
The high renaissance period is the first half of the 16th century which marked its beginning from 1490s and ended by late 15th century. Some of the best known artist of this period were Michelangelo, Raphael, Bramante, Leonardo da Vinci etc. The period of existence of these artist was
a) Leobardo Da Vinci - 1452-1519
b) Michelangelo - 1475-1564
c) Raphael – 1483 -1520
