B My Notes A bowling ball weighing 43.5 N initially moves at a speed of 5.20 m/s. How long must a force of 53.0 N be applied to the ball to stop it? 2. - 25 points ColFunPhys1 8.P.004. My Notes

Answer 1

S. using Newton's and law f = ma (F= 43.SW, a= 9.8 m/s2 . 43.5N = m (9.8) m=44 m = 4-4387 Kg Now, Lets find the Acceleration of the ball due to the force of S3 N. F = ma. S3 = 4.4.377 X CẢ la = 11.94 m/s² Now, we use that accelesation in our equation of motion. We will make a table of values and then choose the most appropriate equation. Vi = 5. 20mis Vf zo a=-11.gq mis? та ? we can use the equation. f = Vitat. & o= 5.20+ (11.90) xt. - + - 0.4355 sec wc
