1 kg is equivilant to about 2.2 lbs. So if you would give 0.1 g per kg, you would convert this to lbs which would give you approx. 0.045 gram/lb. Now simply multiply. 0.045 x 50 = 2.25 grams. =)
thanx so much! im finally starting to get this!
-A person throws a ball upward into the air with an initial velocity of 15 m per second. - How could you calculate how high the ball goes and how long the ball is in the air before it comes to the thrower's hand?
THANK YOU SOO MUCH!! THIS REALLY HELPED!!!
earlier in this forum, marina asked the same question as i did. unfortunately, someone did answer, very clearly, but for some reason i remained to be a little lost. Here is the question: A car traveling 90 km/h is 100 m behind a truck traveling 75 km/h. How long will it take t...
THANX SOO MUCH!! YOU ARE AWESOME!!
Physics Homework _____________________________________________________________ 1.) A particle at t 1 = -2.0 s is at x 1 = 3.4 cm and at t 2 = 4.5 s is at x2 = 8.5 cm. What is its average velocity? Can you calculate its average speed from this data? ____________________________...
physics ---- more help please
this answer is correct but i need the mathematical law needed to solve this problem.
the question is this: suppose you want to design an air-bag system that can protect the driver in an head-on collision at a speed of 100 km/h. estimate how fast the airbag must inflate to protect the driver-- I GOT THE CORRECT ANSWER TO THIS ONE ALREADY. now the second questio...
