Answer:
1.
2.
3.
Explanation:
The velocity vector is
1. The position vector can be found by integrating the velocity vector.
At t = 0, the bird is at the origin, so the integration constants can be determined.
Therefore, C1 and C2 are equal to zero.
2. The acceleration vector is the derivative of the velocity vector with respect to time.
3. We will first find the time when the x-component of the position vector is equal to zero.
We will plug in this value into the y-component of the position vector.
Option (d) is correct. 800 calories of heat is released.
Explanation:
The formula for the heat is given by
Q= m L
Q= heat energy
m= mass =10 g
L= latent heat of fusion=80 cal/gram
so Heat energy= Q= 10 (80)=800 cal
the heat energy is released.
so 800 calories of heat is released.
