Oil-Rich Fish. Oil-rich fish are so called because the oils are distributed throughout the flesh of the fish. Mackerel, herring, salmon and trout are common examples. Occasionally you will find fish classified in a different way: Demersal and Pelagic Fish.
For other uses, see Springbok (disambiguation) . The springbok (Antidorcas marsupialis) is a medium-sized brown and white antelope-gazelle of southwestern Africa. It is extremely fast and can reach speeds of 88 km/h (55 mph) and can leap 4 m (13 feet) through the air.The common name springbok comes from the Afrikaans and Dutch words spring = jump and bok = male antelope or goat.pringbok footprints are narrow and sharp, and are 5.5 cm (2.2 in) long. springbok are distinguished from gazelles in that they only have two premolar teeth in each side of each jaw, instead of three, and therefore a total of twenty eight teeth, rather than thirty.
First thing you have to do is normalize your units. The speed given is in km/h, but should be in m/s so that it jives with the units for acceleration (m/s^2). 111 km/h = 30.833 m/s In any case, the formula for the spring constant is: F=-kx So, we need to find F (force) and x (displacement) in order to find k. Let's find F first: F=ma F=(1440 kg) * (5.0 g) F=(1440 kg) * (5 * 9.8 m/s^2) F=70560 N Now let's find x: x = Vo*t + 0.5at^2 x = (30.833)t + 0.5(5*9.8)*t^2 x = 30.833t + 24.5t^2
