Question

Physics 2701 Lab 4 Velocity 4. Velocity Pre-Lab Read through the lab and then answer the following questions. 1. To the right is a graph of an object's motion. Which is the best interpretation? a) The object is moving with a constant, non-zero acceleration b) The object does not move. c) The objeet is moving with a uniformly increasing velocity. d) The object is moving at a constant velocity. time a uniformly incre The velocity at time t = 2 s is: a) 0.4 m/s b) 2.0 m/s c) 2.5 m/s d) 5.0 m/s e) 10.0 m/s 2· 101 + ÷ 5 time (s)

Explanation / Answer

The object is moving at constant velocity because slope of position -time graph is velocity as the graph is straight line so slope remains same

Slope of graph at t=2s =5/2=2.5

So velocity =2.5m/s
