Skid is driving his classy ride at 90 mi/hr down I-57 to Champaign for his gig at The Blind Pig. Since his Yugo is obviously a custom job, he does not have ABS brakes. While texting Mitch about the set list for the show, he looks up and notices he is about to crash into a stopped car. When he is 170 m from the car he puts on the brakes. (a) Calculate the coefficient of friction Skid needs so that he stops just before he hits the car. (b) If the coefficients of kinetic and static friction are actually 0.3 and 0.6, respectively, and based on what we discussed in class on this topic, is it possible for Skid not to crash into the car

Abatter hits the baseball a with an initial velocity of v0 = 110 ft/sec directly toward fielder b at an angle of 23° to the horizontal; the initial position of the ball is 2.2 ft above ground level. fielder b requires 0.44 sec to judge where the ball should be caught and begins moving to that position with constant speed. because of great experience, fielder b chooses his running speed so that he arrives at the “catch position” simultaneously with the baseball. the catch position is the field location at which the ball altitude is 8.4 ft. determine the velocity of the ball relative to the fielder at the instant the catch is made.
