Question

A particle moves in a straight line with constant speed of 4 m/s for 2 s, then with 6 m/s for 3 s. The average speed of the particle in the given time interval be v. Find [v].(where, [ ] is step integer function)

Answer 1

Step-by-step explanation

Total time, T=2+3=5 s

Total distance, D=4×2+6×3=26 m

Thus, average speed=D/T=26/5=5.2

Thus, [x]=5
