First we need to write the data given in the problem.
Given Data
Distance per day = 125km
Gas cost =1.10 Eu per liter
Car mileage= 37.0 mil/gal
1 Eu= 1.26$
Find
1 week expenditure on Gas =?
Solution
Distance in one week = 125 kmx 7 = 875 km or 543.7 miles
Gas consumed in one week = 543.7/37 = 14.694 gal or 52.99 litre
Answer
Cost of Gas per week = 52.99 x 1.10 = 58.28 Eu or 73.44$

Is there a question in here somewhere?
M = mass of the ball A = 5.0 kg
m = mass of the ball B = ?
V = initial velocity of the ball A before collision = 20 m/s
v = initial velocity of the ball B before collision = 10 m/s
V' = final velocity of the ball A after collision = 10 m/s
v' = final velocity of the ball B after collision = 15 m/s
using conservation of momentum
M V + m v = M V' + m v'
(5.0) (20) + m (10) = (5.0) (10) + m (15)
100 + 10 m= 50 + 15 m
5 m = 50
m= 10 m/s
the force of gravity on planet a is g = 5.72 m/s2
There is an object that weighs 12 kg. The object's weight on Planet A is 69 N. The equation F=mg, where F is the weight, m is the mass, and g is the force of gravity, can be used to calculate the force of gravity on Planet A:
g = F/m
g = 69 N/ 12 kg
g = 5.72 m/s2
<h3>What is the gravity force?</h3>
The force of attraction between any two objects in the universe is known as gravity or gravitational force. The mass of the object and the square of the distance between them determine the force of attraction. The weakest known force in nature, it is by far.
