A bungee cord has a spring constant of 82.5 N/m. After jumping, a person oscillates with a period of 7.50 s. What is the mass of the person? (Unit = kg)​

So since the snail is moving at 3.6  miles per hour you multiply by 5280 to change it into feet per hour. so you get 36*528 ft per hour. since there are 3600 seconds in an hour, you divide 36*528 by 3600. so simplifying we get 528/100 which is 5.28 ft per second

Free body diagram: force of gravity  pointing down, with normal force  with same magnitude, pointing up.in horizontal direction, there is only friction force  , pointing opposite to direction of motion.so the net force comes from friction force (gravity and normal cancel out).===normal force is  friction force is, with  therefore,  andwe have kinematic equationif initial velocity  final velocity acceleration  then16.989 m, or 20 m for one significant figure.
