What two pieces of information do you need to know to get from one location to another?

•• al and bert are jogging side-by-side on a trail in the woods at a speed of 0.75 m/s. suddenly al sees the end of the trail 35 m ahead and decides to speed up to reach it. he accelerates at a constant rate of 0.50 m/s2, while bert continues on at a constant speed. (a) how long does it take al to reach the end of the trail? (b) once he reaches the end of the trail, he immediately turns around and heads back along the trail with a constant speed of 0.85 m/s. how long does it take him to meet up with bert? (c) how far are they from the end of the trail when they meet?

Three-phase, 4-wire panelboards are usually constructed with an even number ofspaces available for each phase; thus, the total number of spaces would be in incre-ments of 6, such as 12, 18, 24, 30, 36, or 42. how many spaces would be available forthe later addition of circuit breakers in panelboard p-1 after the panelboard has been equipped as scheduled?

Using the same approach, determine the magnitude of the magnetic field based on the emf induced at frame 1000, as the loop is exiting the field. note: you need to measure the speed of the loop again–we suggest using a 60-frame interval centered around frame 1000.
