Hey all how u doin. i need help with the following 2 questions.

1. A mass m is given an initial velocity of 'u' in the x-direction. It moves in a medium that resists its motion with a force proportional to the velocity, F = -kv. Find v(x) and how far the far the mass travels before stopping. Find v(t)

2. A ball is thrown horizontally from the top of 150-ft cliff at A with a speed of 50ft/s and lands at point C. Because of a strong horizontal wind, the ball has a constant acceleration in the negative x-direction. Determine the radius of curvature 'p' of the path of the ball at B, where its trajectory makes an angle 45 degrees with the horizontal. i got "normal acc" to be 38. need to check on tht.

p.s. the attached pic is for question 2

thnk u
