A)
Velocity \[(m\text{ }{{s}^{-1}})\] Speed \[(m\text{ }{{s}^{-1}})\] 4 4
B)
Velocity \[(m\text{ }{{s}^{-1}})\] Speed \[(m\text{ }{{s}^{-1}})\] 1.33 1.33
C)
Velocity \[(m\text{ }{{s}^{-1}})\] Speed \[(m\text{ }{{s}^{-1}})\] 4 1.33
D)
Velocity \[(m\text{ }{{s}^{-1}})\] Speed \[(m\text{ }{{s}^{-1}})\] 1.33 4
Correct Answer: D
Solution :
Total distance = 60 m Displacement = 20 m Total time = 15 s Speed\[=\frac{60}{15}=4m\,\,{{s}^{-1}};\] Velocity \[=\frac{20}{15}=1.33m\,\,{{s}^{-1}}\]You need to login to perform this action.
