Acceleration of the car is 3.375 m/s² and the force of the car moving forward is 5062.5 N
Explanation:
- Acceleration is the rate of change of velocity.
- It is given by the equation, a = change in velocity/time
Here, velocity changes from 0 to 27 m/s and time = 8
⇒ Acceleration = 27 - 0/8 = 27/8 = 3.375 m/s²
- Force is calculated by the equation, F = Mass × Acceleration
- This is based on Newton's second law of motion.
Here, mass of the car = 1500 kg and a = 3.375 m/s²
⇒ Force = 1500 × 3.375 = 5062.5 N
At the top, due to the fact that POTENTIAL energy is Stored energy.
Answer:
6.384 m/
Explanation:
The velocity is given by;
We know;
PE= mgh
KE= 1/2 m
but KE=PE
==> 1/2 m =mgh
==> 1/2 =gh
==> 
puting g=9.8 m/sec2
h=2.08 m
==> 
=
According to Newton's 3rd law, for every force applied, there's an equal and opposite force that will occur. So when you are walking , you are pushed forward but the plain is "pushed back" from the force
Explanation:
- A force is a push or a pull that acts upon an object as a results of its interaction with another object. Forces result from interactions.
- The statement means that in every interaction, there is a pair of forces acting on the two interacting objects. The size of the forces on the first object equals the size of the force on the second object. The direction of the force on the first object is opposite to the direction of the force on the second object. Forces always come in pairs - equal and opposite action-reaction force pairs.
- According to Newton, whenever objects A and B interact with each other, they exert forces upon each other.
- A variety of action-reaction force pairs are evident in nature.
