A1000 kg car is rolling slowly across a level surface at 1m/s, heading toward a group of small innocent children.
the doors are locked, so you can't get inside to use the brakes.
instead, you run in front of the car and push on the hood at an angle of 30° below horizontal.

how hard must you push to stop the car in a distance of 2 m?

Aball has an initial velocity of 3 m/s. if there is no friction, what is the highest it could roll?

Both independent and dependent clauses

Calculate the minimum energy required to remove one proton from the nucleus 126c. this is called the proton-removal energy. (hint: find the difference between the mass of a 126c nucleus and the mass of a proton plus the mass of the nucleus formed when a proton is removed from 126c.) express your answer with the appropriate units. emin e m i n = nothing nothing request answer part b how does the proton-removal energy for 126c compare to the binding energy per nucleon for 126c, calculated using eb=(zmh+nmn−azm)c2?
