q.3. a truck moves from a to d along the path as shown below. what is the trucks distance and displacement? a) distance = 21 km displacement = 21 km to the north b) distance = 5 km displacement = 5 km to the north c) distance = 5 km displacement = 21 km to the south d) distance = 21 km displacement = 5 km to the south

q.3. a truck moves from a to d along the path as shown below. what is the trucks distance and displacement? a) distance = 21 km displacement = 21 km to the north b) distance = 5 km displacement = 5 km to the north c) distance = 5 km displacement = 21 km to the south d) distance = 21 km displacement = 5 km to the south

Answer

Explanation:

Step1: Define distance and displacement

Distance is total path length, displacement is straight - line distance from start to end with direction.

Step2: Calculate distance

Count the number of 1 - km segments on the path. From A to B, B to C, C to D, assume each side of the rectangle - like path has lengths such that the total number of 1 - km segments is 5 km. So distance = 5 km.

Step3: Calculate displacement

The start point is A and the end - point is D. The straight - line distance from A to D is 5 km in the south direction. So displacement = 5 km to the South.

Answer:

c) distance = 5 km, displacement = 5 km to the South
