Answer:
For every action, there is an equal and opposite reaction.
Explanation:
Let's say I threw a ball on the wall. The image shows the instance the ball comes into contact with the wall.
If you would look at the image above,
- F1 and F2 are acting in opposite directions.
- They both have the same magnitude too.
F1 is the force of the ball on the wall (action force) and F2 is the force of the wall on the ball (reaction force). This is called an action-reaction pair.
Answer:
8.87 gallons of kerosene
Explanation:
Step 1: Given and required data
- Energy to travel by plane per passenger trip: 1,260 MJ/passenger trip
- Energy per gallon of kerosene: 142 MJ/gal
Step 2: Calculate how many gallons of kerosene it takes to make the trip by plane
We can calculate the amount of kerosene required by combining the factor provided in Step 1.
1 gal/142 MJ × 1,260 MJ/passenger trip = 8.87 gal/passenger trip
8.87 gallons of kerosene are required to make the trip by plane.
Answer:
the final velocity of the cart is 30 m/s
Explanation:
Given;
initial velocity of the cart, u = 10 m/s
distance moved by the cart, d = 200 m
acceleration of the cart, a = 2.0 m/s²
The final velocity of the cart is calculated as;
v² = u² + 2ad
where;
v is the final velocity
v² = 10² + 2(2)(200)
v² = 900
v = √900
v = 30 m/s
Therefore, the final velocity of the cart is 30 m/s
