Problem 3.2 Part A Draw the vector C⃗ =A⃗ +B⃗ .(Figure 1)
1 answer:
I can't answer this question without a figure. I've found a similar problem as shown in the first picture attached. When adding vectors, you don't have to add the magnitudes only, because vectors also have to factor in the directions. To find the resultant vector C, connect the end tails of the individual vectors. <em>The red line (second picture) represents the vector C.</em>

The acceleration of the skier over the distance traveled is 10.38 m/s²
The given parameters;
- Initial velocity of the skier, u = 56 m/s
- Distance covered by the skier, s = 151 m
Acceleration is defined as the change in velocity per change in time of motion.
The magnitude of the acceleration of the skier is calculated as follows;
where;
<em>v is the final velocity at the end of 151 m = 0</em>
Thus, the acceleration of the skier over the distance traveled is 10.38 m/s²

Answer:
53,130 J
Explanation:
When a certain substance absorbs heat, the temperature of the substance increases according to the equation:
where
Q is the amount of heat absorbed
m is the mass of the substance
C the specific heat capacity
the change in temperature of the substance
In this problem:
m = 2.3 kg is the mass of copper
is the increase in temperature
is the specific heat of copper
So, the amount of heat absorbed is:
