Answer:
Equal
Explanation:
The law of conservation of energy states that the total momentum before and after a collision are equal
given that initial speed of the car is

now after travelling the distance d = 1.8 * 10^1 m the car will stop
so here we can use kinematics to find the acceleration of car


here we have


net force applied due to brakes of car is given by Newton's II law

here we have
mass = 1.2 * 10^3 kg


now we can say



So the force applied due to brakes is given as above
Answer:
A-Z
Explanation:
A proton has an estimated weight of 1.
F=ma
Force is 50N. Acceleration is 25 m/s^2.
50N=m*25 m/s^2
Divide both sides by 25.
mass=2 kg
Sustainable buildings are generally less expensive over the lifetime of the building, due to lower energy costs in production of the materials and lower energy bills. Option A is correct.
<h3>What is sustainable buildings? </h3>
Sustainable buildings refer to both a structure and the implementation of environmentally responsible and resource-efficient methods.
Sustainable buildings are generally less expensive over the lifetime of the building, due to lower energy costs in production of the materials and lower energy bills,
Hence,option A is correct.
