Stuck finding out the manual solution for finding x in this logarithmic equation
Good day,
I got stuck finding the manual solution for this problem without relying to the solve function of Casio calculator
The original equation was
[(1+x)40] -1 = (181205.95/3000)x
Then I tried using properties of logarithm and I simplified it to this equation:
[ln(181205.95/3000)]/40 = ln(1+x) - (1/40)[ln(x+3000/181205.95)]
0.102526 = ln(x+1) - 0.025ln(x+0.0165557)
Answer: x = 0.02
Find the complete or particular solution of the followiing D.E.

a soccer ball with mass 0.420 kg is initially moving with speed 2.00 m/s. a soccer player kicks the ball, exerting a constant force of magnitude 40.0 N in the same direction as the ball's motion. over what distance must the player's foot be in contact with the ball to increase the ball's speed to 6.00 m/s?

a force of a baseball swing. a baseball ha mass 0.145 kg
a. if the velocity of a pitched ball has a magnitude of 45.0 m/s and the batted ball's velocity is 55 m/s in the opposite direction, find the magnitude of the change in momentum of the ball and of the impulse applied to it by the bait.
b. if the ball remains in contact with the bat for 2 m/s, find the magnitude of the average force applied by bat.

Applications Of Differential Equations
The radial stress p at distance r for the axis of the thick cylinder subjected to internal pressure is given by p + r (dp/dr) = A − p where A is a constant. If p = p0 at the inner wall r = r1 and is negligible (p = 0) at the outer wall r = r2 find an expression for p.
