As you walked on the moon, the earth’s gravity would still pull on you weakly and you would still have an earth weight. How larg

e would that earth weight be, compared to your earth weight on the earth’s surface? (Note: The earth’s radius is 6378 km and the distance separating the centers of the earth and moon is 384400 kilometers.)

Answer:

g_2 =2\times 10^{-4}g      

Explanation:

given,

radius of earth = 6378 km

distance separating the center of the earth and moon =  384400 km

we know acceleration due to gravity

g = \dfrac{Gm}{r^2}            

g_2 = g\dfrac{r^2}{R^2}                

g_2 = g\dfrac{6378^2}{384400^2}              

g_2 =2\times 10^{-4}g      

hence, the weight of earth compared to the your weight on earths surface is equal to 2 × 10⁻⁴ g.

Aloiza [94]

Answer:

It is equal to the overall momentum before collision, so far no external object is involved.

Explanation:

Momentum is always conserved during collision as a rule. This is equal to the product of the mass and velocity. Thank you.

A hockey puck with mass 0.3 kg is shot across an ice-covered pond. Before the hockey puck was hit, the puck was at rest. After t
JulsSmile [24]

Answer:

The net friction force is 8.01 N

Explanation:

Net friction force = mass of hockey puck × acceleration

From the equations of motion

v^2 = u^2 + 2as

v = 40 m/s

u = 0 m/s (puck was initially at rest)

s = 30 m

40^2 = 0^2 + 2×a×30

60a = 1600

a = 1600/60 = 26.7 m/s^2

The acceleration of the puck is 26.7 m/s^2

Net friction force = 0.3 × 26.7 = 8.01 N
