Answer:
vf = 11.2 m/s
Explanation:
m = 10 Kg
F = 2*10² N
x = 4.00 m
μ = 0.44
vi = 0 m/s
vf = ?
We can apply Newton's 2nd Law
∑ Fx = m*a (→)
F - Ffriction = m*a ⇒ F - (μ*N) = F - (μ*m*g) = m*a ⇒ a = (F - μ*m*g)/m
⇒ a = (2*10² N - 0.44*10 Kg*9.81 m/s²)/10 Kg = 15.6836 m/s²
then , we use the equation
vf² = vi² + 2*a*x ⇒ vf = √(vi² + 2*a*x)
⇒ vf = √((0)² + 2*(15.6836 m/s²)*(4.00m)) = 11.2 m/s
What effect man there are a million effects the only one that arent true are fusion or fission and magnetism unless that bowling ball is iron
Both answers are going to be C
Answer:
2.4086 * 10^(-4) m^3
Explanation:
Volume of sphere = 4/3 * pi * r1^3
Volume of cylinder = pi*r2^2*h
r1 = 0.05 m
r2 = 0.03 m
Hence,
Resulting Volume = Volume of sphere - Volume of cylinder
