PHYSICS:
1. Plan to go to a place by a vehicle. Take reading of odometer and speedometer after every 5 minutes till you
reach your destination. Record these observations in tabular form, plot graph between distance - time and
speed-time. State whether this motion is uniform or non-uniform. Also calculate the average speed of your
journey.
Answers
Answer:
Motion is non-uniform
Average speed = 40.5 km/Hr
Explanation:
Plan to go to a place by a vehicle. Take readings of odometer and speedometer after every 5 Minutes till you reach your destination. Record these observation in tabular form; plot graphs
Time (in Mins) Odometer (km) Speedometer (Km/Hr)
0 0 0
5 2 30
10 5 50
15 9 50
20 13 60
25 18 60
30 22 50
35 25 30
40 27 0
Motion is not uniform
Motion is non-uniform
Total Distance = 27 km
Time = 40 mins = 40/60 = 2/3 hr
Average speed = 27/(2/3) = 81/2 = 40.5 km/Hr
