The metal aluminum coils in an air conditioner conduct thermal energy from inside the house and release it outside the house. What can be said about the coils when they are accepting the heat inside the house? They must be warmer than the air inside the house. They must be cooler than the air inside the house. They must have more thermal energy than the air inside the house. They must be more insulated than the air inside the house.

The magnitude and direction of the rocket acceleration is 68.89 m/s² upward.

The speed of the rocket at the given elevation is 186 m/s.

Explanation:

Given;

time to reach the given height, t = 2.7 s

height reached, h = 93 m

initial velocity of the rocket, u = 0

The magnitude and direction of the rocket acceleration is calculated as;

h = ut + ¹/₂at²

h = 0 + ¹/₂at²

h = ¹/₂at²

a = 2h / t²

a = (2 x 93) / 2.7

a = 68.89 m/s²

the direction of the acceleration is upward.

The speed at this elevation, V = u + at

V = at

V = 68.89 x 2.7

V = 186 m/s
