Someone please help me it’s due tomorrow 1) How do we calculate the momentum of a race car? What part of this changes during a collision?

2) What happening to the momentum of the car when they crash?

3) how does impulse factor into this?

4) what type of collision is it ( ideally) when cars crash into this SAFER barrier?

Cyclotrons are widely used in nuclear medicine for producing short-lived radioactive isotopes. these cyclotrons typically accelerate h- (the hydride ion, which has one proton and two electrons) to an energy of 5 mev to 20 mev. this ion has a mass very close to that of a proton because the electron mass is negligible—about 1 2000 of the proton’s mass. a typical magnetic field in such cyclotrons is 1.9 t. (a) what is the speed of a 5.0-mev h-? (b) if the h- has energy 5.0 mev and b = 1.9 t, what is the radius of this ion’s circular orbit?
