Suppose the mass of a fully loaded module in which astronauts take off from the Moon is 12,900 kg. The thrust of its engines is

Alexandra [31]

Answer:

Acceleration a=0.5 m/s²

Explanation:

Given data

Mass m=12,900 kg=1.29×10⁴kg

Thrust of engine F=28,000 N=2.8×10⁴N

gravitational acceleration g=1.67 m/s²

To find

Acceleration

Solution

As we know that

$W_{weigth}=mg\\ W=(1.29*10^{4}kg )(1.67m/s^{2} )\\W=21543N$

The net force can be given as

$F_{net}=F_{thrust}-W\\F_{net}=(2.8*10^{4}-21543)N\\ F_{net}=6457 N$

From Newtons second law of motion we know that

$F=ma\\a=F/m\\a=\frac{6457N}{12,900kg}\\ a=0.5m/s^{2}$

A cat chase a mouse across a 1.0 m high table. The mouse steps out of the way, and the car slides off the table and strikes the

Tema [17]

The cat fell 1.0 m from the ground.

Using the formula

$h = v_{oy}t - \frac{gt^2}{2}$

Here, $v_{oy} = 0, \; h = 1.0 \; m.$

Solving for t, the time it spent in the air is

$t = \sqrt{\frac{2h}{g}} = \sqrt{\frac{2(1.0 \; m)}{9.8 \; m/s^2}} = 0.451753951 \; s$

The cat does not accelerate along the horizontal, so it has constant horizontal velocity. Since it strikes the floor 2.2 m from the table, then

$v_x = \Delta x/t = \frac{2.2\; m}{0.451753951 s} = 4.869907597 \; m/s \Rightarrow 4.9 \; m/s$
