You use 35j of energy to move a 7n object. How far did you move it ?
1 answer:
5m
Explanation:
Given parameters:
Energy = 35J
Force on object = 7N
Unknown:
Distance moved = ?
Solution:
The energy on the car will cause the car to do work . When work is done, a force moves a body in particular distance. We can see that energy and force are related:
Energy = force x distance
Distance =
Inputting the parameters:
Distance = = 5m

Answer:
The workdone is
Explanation:
From the question we are told that
The potential difference is
Generally the charge on is
Generally the workdone is mathematically represented as
=>

The total momentum of the system is equal to 50 Kgm/s.
<u>Given the following data:</u>
- Mass 1 = 80 kg
- Velocity 1 = 2 m/s east.
- Mass 2 = 70 kg
- Velocity 2 = 3 m/s west.
To determine the total momentum of the system:
Mathematically, momentum is given by the formula;
<u>For Football player 1:</u>
Momentum 1 = 160 Kgm/s.
<u>For Football player 2:</u>
Momentum 1 = 210 Kgm/s.
Now, we can calculate the total momentum of the system:
Total momentum = 50 Kgm/s.
<u>Note:</u> We subtracted because the football players were moving in opposite directions.

The equation for force is F=ma. Because we have the value of mass (0.42 kg) and the acceleration (14.8 m/s^2), simply plug them into the equation for force to get
The answer is 6.22 N because newtons are the unit used to measure force.
The answer is 6.22 N because newtons are the unit used to measure force.
