Answer to Question #247104 in Classical Mechanics for Emmanuel

Question

Sketch the position-time, velocity- time, and acceleration-time graph of:

A. An object at rest moving at a constant velocity of 5m/s? What is the instantaneous velocity of the object at 3s? What is the position of the object at 15s? What is the slope?

B. An object moving with a constant acceleration of 5m/s^2
C. An object at the position of 10 m remains at its position over 10s? What is the instantaneous velocity of the object at 2s? What is the position of the object at 7s? What is the slope?

Answer 1

A)

$v_3=v=5~\frac ms,$

$x_{15}=75~m,$

B)

C)

$v_2=0~\frac ms,$

$x_7=10~m,$
