A 8.34 × 103-kg lunar landing craft is about to touch down on the surface of the moon, where the acceleration due to gravity is
Mnenie [13.5K]

Answer:

21870.3156 N

Explanation:

u = Initial velocity

v = Final velocity

s = Displacement

a = Acceleration

g = Acceleration due to gravity = 1.6 m/s²

Equation of motion

v^2-u^2=2as\\\Rightarrow a=\frac{v^2-u^2}{2s}\\\Rightarrow a=\frac{0^2-18.2^2}{2\times 162}\\\Rightarrow a=-1.02234\ m/s^2

The acceleration of the craft should be 1.02234 m/s²

F=ma\\\Rightarrow F=8.34\times 10^3\times 1.02234\\\Rightarrow F=8526.3156\ N

Weight of the craft

W=mg\\\Rightarrow W=8.34\times 10^3\times 1.6\\\Rightarrow W=13344\ N

Thrust

F_t=F+W\\\Rightarrow F_t=8526.3156+13344\\\Rightarrow F_t=21870.3156\ N

The thrust needed to reduce the velocity to zero at the instant when the craft touches the lunar surface is 21870.3156 N

By riding an elevator up 200 m, a person’s GPE increases by 164,000 J. What is  the person’s mass?
Andrew [12]

Answer:

Person’s mass M = 83.67 kg (Approx.)

Explanation:

Given:

Gravitational potential energy = 164,000 J

Height = 200 m

Find:

Person’s mass M

Computation:

Gravitational acceleration g = 9.8 m/s²

Gravitational potential energy = mgh

164,000 = (m)(9.8)(200)

Person’s mass M = 83.67 kg (Approx.)
