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

The answer to your question is C. <span> the Sun's strong gravitational field . This is correct because i took the test :D</span>
Hello!
A car travels 35.0 mph north for 1.00 hour, then 40.0 mph east for 0.0500 hour, and finally 50.0 mph northeast for 2.00 hours. Calculate the average speed.
We have the following data:
* velocity (in mph)
(V1) = 35.0 mph
(V2) = 40.0 mph
(V3) = 50.0 mph
* weights for the time (in hours)
(T1) = 1.00 hour
(T2) = 0.0500 hour
(T3) = 2.00 hours
We apply the data to the weighted average formula to find the average speed, let us see:






Answer:
The Average Speed is approximately 44.92 mph
