There is 4000 balls in the earth of the world why is that so hard for you
Answer:
a. a= 1.029 ms⁻²
b. S=25.89 m
Explanation:
given
initial speed is u = 7.30 m/sec
final speed is v = 0 m/sec
mu_k = 0.105
kinetic frictional force is Fk = mu_k×m×g
mu_k×m×g = m×a
m cancels
mu_k×g = a
deccelaration a = mu_k×g = 0.105×9.8 =1.029 ms⁻²
b) using v²-u² = 2aS
0²-7.3² = -2×1.029×S
53.29=2.058×S
S = 53.29/2.058
S=25.89 m
The law of conservation of energy is a law that states that "energy cannot be created or destroyed, only changed" this means that you can't create it or destroyed as in, if you burn wood, you have released the energy. you haven't destroyed it, you have just released it
Be because it’s the answer
The answer is A
