You drive in a straight line at 22 m/s for 12 miles, then at 30 m/s for another 12 miles. (a) How does your average speed sav co
Setler [38]

Answer:

Explanation:One method of calculating average speed is to divide the total distance by the total time spent

d1=d2= 12 miles

d1=d2= 19312.1 m

t1=\frac{d1}{u1} \\t1=19312.1/22\\t1=877.8 secs

t2=\frac{d2}{u2} \\t2=19312.1/30\\t2=673.7 secs

u_a=\frac{d1+d2}{t1+t2} \\u_a=25.385 m/s

There is slight difference between the average speeds  due to the reason that average speed is not just the midpoint of the speed but is the total distance traveled by total time.

Draw the following vector: 350 N, 30° south of east [1 cm = 50 N]
tiny-mole [99]

The magnitude and the position of the 350 N vector can be represented using arrow pointing out from the South-East of a Cartesian coordinate.

The given parameters:

  • Magnitude of the vector = 350 N
  • Position of the vector = 30⁰ South east

The vector is represented with arrow pointing out from south-east represented in a Cartesian coordinate.

  • The length of the arrow represents the magnitude of the vector which is 350 N.
  • The direction of the arrow indicated by the arrow head represents the position of the vector.
  • The position of the vector is 30 degrees South of East.

Thus, the magnitude and the position of the 350 N vector can be represented using arrow pointing out from the South-East of a Cartesian coordinate.
