Answer:

Speed and velocity both measure an object’s rate of motion. However, speed is a scalar quantity, which means that it can be described with a numerical value. Velocity is a vector quantity, which depends on direction as well as magnitude. Read these definition for more information:

speed - the rate of distance traveled by a moving object over time

velocity - the rate of displacement of a moving object over time

Basically, an object’s speed tells you how fast it’s going. Its velocity tells you how fast it’s going in a certain direction. You use speed measurements in your daily life, but physicists depend on velocity measurements more frequently in their work.

41. City A lies 30 km directly south of city B. A bus, beginning at city A travels 50 km at 37° north of east to reach city C. H

Nana76 [90]

Answer:

B) 40 km West

Explanation:

Let position of B is origin so with respect of City B the position of A is given as

$r_A = 30 km$ south of city B

now Bus starts from City A and travels a distance of 50 km at 37 degree North of East to reach city C

so it is

$r_{CA} = 50(cos37\hat i + sin37 \hat j)$

$r_{CA} = 40\hat i + 30\hat j$

now the position of C is given with respect to A

in order to find the position of C with respect to B we can say

$r_C = r_{CA} + r_A$

$r_C = 40\hat i + 30\hat j + (-30 \hat j)$

$r_C = 40 \hat i$

so in order to reach at city B from city C bus has to travel 40 km towards West

An object moves from point A to B to C to D and finally to A

Nataly [62]

here's the solution,

The radius of the circle = 3 km

distance covered = circumference of the circle,

So, Circumference :

=》

$2\pi r$

=》

$2 \times 3.14 \times 3$

=》

$18.84$

(a). Distance covered by moving object is 18.84 km

(b). 0 km

now, Displacement of the object is 0 km, because displacement is the shortest distance from stating point to the destination, but the object returns back to the starting point, hence magnitude of displacement is 0.
