Answer:
900
Explanation:
v = s / t = 9000m / 10 s = 900m/s
Answer:
Explanation:
a is the acceleration
μ is the coefficient of friction
Acceleration of the object is given by

Velocity at the bottom

after travelling 4m , its velocity becomes 0



Coefficient of kinetic friction
μ = F/N

Therefore, the Coefficient of kinetic friction is 0.31
current in 3ohm resistor is 0.9
