it's alright ok fine ! no problem you most welcome!
Answers:
1) Time it takes to travel to the moon
Velocity 
is defined as:
Where:
is the average distance from Earth to the Moon
is the velocity of the spacecraft
the time
Isolating :
This is the time in hours
2) Time in days
A day is equivalent to 24 hours:
Hence:
This is the time in days
3) Time in months
A month is equivalent to 30.4 days:
Hence:
This is the time in months
Answer:
Explanation:
In order to calculate the change of any quantity you must substract the initial value of that quantity from the final value of the same quantity.
The concept of momentum is defined as,
Momentum = mass×velocity
So we calculate the change of momentum as,
Momentum change = final momentum - initial momentum
= mv - mu =m(v-u)
Where v = final velocity
u = initial velocity
m = mass of the object
So to calculate the momentum change of the car,
Change in momentum of the car = 1000×(8-1) = 1000×7 = 7000 Ns
