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 xdirection. 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 150ft 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 xdirection. 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
