Answer:
- 0.25m/s²
Explanation:
Given parameters:
Initial velocity = 40m/s
Final velocity = 30m/s
Time taken = 40s
Unknown:
Acceleration of the car = ?
Solution:
Acceleration is the rate of change of velocity with time.
So;
Acceleration =
Acceleration =
= - 0.25m/s²
This implies that the car will decelerate at a rate of 0.25m/s²
Can u show the problem ?
Acceleration= the rate and change of an object also cars go fast so I think it would be positive acceleration
Hope I helped
Explanation:
It is given that,
Power consumed by toaster oven, 
Time taken, t = 6 minutes = 0.1 hour
Energy used by toaster, 

Similarly,
Power consumed by toaster oven, 
Time taken, t = 9 minutes = 0.15 hour
Energy used by toaster, 

Hence, this is the required solution.
Answer:
Potential energy plus kinetic energy equals mechanical energy because mechanical energy is basically just all of an object's energy, it's just two kinds of energy. The potential is stored inside and kinetic is being used. Both of those together is the total amount of the objects energy, which is the mechanical energy.
