A baseball player is approaching home plate with a speed of 5.8m/s when he decides to slide
A baseball player is approaching home plate with a speed of 5.8m/s when he decides to slide. He slides for 1.1s, just reaching the plate safe. What is the magnitude and direction of the player's acceleration? How far did he slide?His magnitude of acceleration is5.8/1.1= 5.3 m/s^2How far did he slide? I'm guessing you calculate x = 1/2a*t^2 which equals 6.4mI don't know how to find the direction since no direction is really given. Also correct me if I'm wrong...
