(a) what is the speed of a supersonic aircraft with a 17.0-m wingspan, if it experiences a 1.60-v hall voltage between its wing tips when in level flight over the north magnetic pole, where the earth’s field strength is 8.00×10−5 t

In all trials, the magnitude of the final velocity for g1 + g2 was less than the magnitude of any initial velocity. as mass increased, what happened to the velocity? the velocity decreased. the velocity increased. the velocity of g1 + g2 could not be measured. the velocity was not affected by the mass increase.

Find v(t), given acceleration a(t)=7j and initial velocity v(0)=k

Consider a system to be two train cars traveling toward each other. what is the total momentum of the system before the train cars collide?   kg • what must the total momentum of the system be after the train cars collide?   kg •
