Answer to Question #100176 in Mechanics | Relativity for Semira

Question

Displacement(m) 0 20 40 40 80 80 60 40 0
Time (s) 0 10 20 30 40 50 60 70 80
Explain the different sections of the graph in as much as you can

Answer 1

1)    t=0…20: body is moving with speed 2 m/s in the direction x

2)    t=20…30: body does not move

3)    t=30…40: body is moving with speed 4 m/s in the direction x

4)    t=40…50: body does not move

5)    t=50…70: body is moving with speed 2 m/s in the opposite direction to x

6)    t=70…80: body is moving with speed 4 m/s in the opposite direction to x
