Carboplatin (c6h12n2o4pt) is a platinum-containing
compound that is used to treat certain forms of cancer.
this compound contains 52.5% platinum. if the price
for platinum is $1047/troy ounce, what is the cost of
the platinum in 2.00 g of this compound? a troy ounce
is equal to 480 grains, and one grain is equal to 64.8 mg.

a chemical reaction

explanation:

(newtons first law)

conservation of momentum law states :

momentum before collision = momentum after collision

momentum p (kg-m/s)= mass * velocity

say moving car=1 000 kg, velocity = 10 m/s then p = 1 000*10= 10 000 kg-m/s

say still car = 2 000 kg, velocity = 0 m/s then p = 2 000* 0 = 0 kg-m/s

total momentum prior to collision = 10 000 + 0 = 10 000 kg-m/s

momentum after collision = 10 000 kg-m/s

mass now = 1 000 kg+2 000 kg = 3 000 kg

10 000 = 3 000 kg* velocity m/s

10 000/3 000 = velocity

3.33 m/s = velocity after collision

an impulse is a force applied over time , momentum is exclusive of external forces and a perfect collision is implied
