Answer:
Exercise 1
Use the diagram to determine the resulting displacement and the distance traveled by the skier during these three minutes
Distance travelled from B to C = 420
Distance travelled from C to D = 105
Total Distance = 247
Displacement = 140 m , rightward
Exercise 2
What is the coach's resulting displacement and distance travel?
Distance B to C = 20
Distance from B to D = 20
Distance from C to D = 40
Displacement = 55 yards , left
C. Assessment / Application / Outputs
1. A whale swims due east ( from 0km) a distance of 5km, turns around and goes due west for 2km and finally turns around again and heads 4km due east.
a. what is the total distance traveled ?
0km + 5km + 2km + 4km = 11km
b. what is the displacement ( change in positions) ?
5 + ( -2) + 4 = 7km due east
2. Complete the table below. Based on the given motions, give the distance traveled and the object's displacement.
An object moves from point 1 to point 4 then reverses and ends at point 2
Distance traveled : 5
Displacement : 1
An object moves from point 1 to point 5 then reverses to point 2
Distance traveled : 7
Displacement : 1
An object moves from point 1 to point 3 then reverses to 0
Distance traveled : 5
Displacement : -1
An object moves from point 3 to point 5 and then reverses to point 1
Distance traveled : 6
Displacement : -2
An object from point 2 to point 4 and reverses to point 2
Distance travelled : 4
Displacement : 0
