In 1967, one of the high school football teams in California had a tacklenamed Bob whose mass was 2.20 × 102 kgSuppose that after winning agame the happy teammates throw Bob up in the air but fail to catchhim.When Bob hits the ground, his average upward acceleration overthe course of the collision is 75.0 m/s2(Note that this acceleration has amuch greater magnitude than free-fall acceleration.) Find the averageforce that the ground exerts on Bob during the collision.and I also need help withThe whale shark is the largest type of fish in the worldIts mass can beas large as 2.00 × 104 kg, which is the equivalent mass of three averageadult elephantsSuppose a crane lifts a net with a 2.00 × 104 kg whaleshark off the groundThe net is steadily accelerated from rest over aninterval of 2.5 s until the net reaches a speed of 1.0 m/sCalculate themagnitude of the tension in the cable pulling the net.Thanks/ Too confusing.
You are right about the Champoin plugsTHey should be of the market by nowAnyway, try a magnet on a stick, like an antennaMany auto parts stores have thisSTick it right into the spark plug hole and hope for the bestYou will have to use a different plug socket to remove the remnantsAs long as the hex part is there, you should be able to remove itSpray with PB blasterTry a different wrenchIt WILL come out!! Use Boch platinum or fusion plugs in this carThey make more power and give better MPG'sGood luck!!
Problem 1: Force (mass)(acceleration) (220 kg)(75.0 m/s^2) 16500 N Problem 2: acceleration (change in velocity)/(time) (1.0 m/s)/(2.5 s) 0.40 m/s^2 Force (mass)(acceleration) (2.00x10^4 kg)(0.40 m/s^2) 8000 N
