The object travels 16m in 4s and then another 16m in 2s. What is the average speed of the object?
Step 1: Given data
Distance traveled(d1) = 16 m, Time taken(t1) = 4 sec
Distance traveled(d2) = 16 m, Time taken(t2) = 2 sec
Let vavg be average speed.
Step 2: Formula used
vavg=TotalDistanceTotaltime
Step 3: Finding average speed
Total distance(D),(d1+d2)=16m+16m=32m
Total time(T)= (t1+t2)=4s+2s=6s
vavg=TotalDistanceTotaltime=32m6s=5.33ms .
Hence, the average speed of the object is 5.33m/s.
