Answer:

3.9×10⁸ m

Explanation:

If x is the distance between the Earth and the Moon, the the light travels a distance of 2x in 2.6 seconds.

Distance = rate × time

2x = (3×10⁸ m/s) (2.6 s)

x = 3.9×10⁸ m

in a closed system three objects have the following momentum: 11 kg* m/s, -65 kg*m/s and -100 kg m/s. the objects collide and mo

guajiro [1.7K]

Explanation:

The momentum of the three objects are as follow :

11 kg-m/s, -65 kg-m/s and -100 kg-m/s

Before collision, the momentum of the system is :

$P_i=11+(-65)+(-100)\\\\P_i=-154\ kg-m/s$

After collison, they move together. It means it is a case of inelastic collision. In this type of collision, the momentum of the system remains conserved.

It would mean that, after collision, momentum of the system is equal to the initial momentum.

Hence, final momentum = -154 kg-m/s.

A car travels along the motorway at a steady 70 m.p.h. How far will it travel in half an hour?

Sergeu [11.5K]

If a car is travelling 70 m.p.h that means it is travelling 70 miles PER HOUR and since we want to know half an hour we can do

70mph divided by 2 =35m.p half hour so the car is travelling 35miles in half an hour
