Answer:
i belive 1 m/s
Explanation:
dividing displacement from time it should be 1 cuz 5/5 is 1
please tell me if right!
Answer:
v = -24.5 m/s
Explanation:
Use conservation of momentum P = m*v. Unless there are external forces involved, total momentum must be conserved.
P: momentum
m: mass
v: velocity
1. calculate the total momentum before the collision:

2. the total momentum after the collision must not change:

3. after the collision the velocity of the car is the same as the velocity of the truck:

4. combining 2. and 3.:

5. this equation only has one unknown and can be solved for v:


The answer should be the letter C...
The magnitude of the applied force is 3369.57 N.
<h3>What is Force?</h3>
Force can be defined as the product of mass and acceleration.
To calculate the magnitude of the applied force, we use the formula below.
Formula:
- P = Fv................ Equation 1
Where:
- P = Power of the electric motor
- F = Applied force
- v = Velocity
Make F the subject of the equation
- F = P/v................. Equation 2
From the question.
Given:
- P = 31 kW = 31000 W
- v = 9.2 m/s
Substitute these values into equation 2
- F = 31000/9.2
- F = 3369.57 N
Hence, the magnitude of the applied force is 3369.57 N.

To find the acceleration, we would need to use the equation acceleration= final velocity- initial velocity/elapsed time. Since the final velocity is 35 and the initial velocity is 65, we can subtract 65 from 35 first, which gives us -30. Then if we divide that by the elapsed time, which is 10, we get -3. Your acceleration is -3 meters per second.
Hope this helps! :D
