A ) decrease.
B ) increase.
C ) increase, then decrease.
D ) not change.
The answer is A) decrease
Take pushing a box, for example-- You push your hardest then give out, still trying to push the box. You are doing less work than what you have started with!

The velocity is 1100 kilometers per hour
Given: Mass m = 5.00 Kg; Height h = 12 m; Time t = 15 s
Required: Power P = ?
Formula: P = Fd/t = mgh/t
P = (5.0 Kg)(9.8 m/s²)(12 m)/15 s
P = 39.2 Kg.m²/s² or
P = 39.2 J
The calculated mutual inductance is 8.544 x 10⁻⁵ H.
Two coils have a mutual inductance of 1 henry when emf of 1 volt is induced in coil 1 and when the current flowing through coil 2 is changing at the rate of one ampere per second.
Length of the solenoid= 5.0 cm
Area of cross-section=1.0 cm²
no of spaced turns=300 turns
turns of insulated wire=180 turns
Mutual inductance (M) = μ₀μr N1N2 A/ L
=(4xπx 10⁻⁷) x (6.3 x 10⁻³) x 300 x 180 x 1/ 5
=79.12 x 10⁻¹⁰ x 54000 / 5
=8.544 x 10⁻⁵ H
hence, the mutual inductance is 8.544 x 10⁻⁵ H.

Answer:
The maximum height will be 7408.8 meters
Explanation:
final velocity = initial velocity + acceleration × time
final velocity = 0 m/s + 58.8 m/s^2 ×6 s
Final velocity = 352.8 m/s
final velocity ^2 = initial velocity ^2 + 2 × acceleration × displacement
(352.8)^2 = (0)^2 + 2×58.8 ×displacement
Solving for displacement,
height = 1058.4 meters.
After this, the rocket is in free fall, we can use the same equation.
final velocity ^2 = initial velocity ^2 + 2 ×acceleration×displacement
final velocity = 0
0^2 = 352.8^2 + 2×(-9.8)×displacement
displacement = 6350.4 meters
the maximum height will be 7408.8 meters
