Question

Constants Periodic Table Part A You are walking to your physics class at speed 1.1 m/s with respect to the ground. Your friend leaves 2.0 min after you and is walking at speed 1.3 m/s in the same direction. How fast is she walking with respect to you? Express your answer with the appropriate units 0.20 m Correct Part B How far does your friend travel before she catches up with you? Express your answer with the appropriate units. d- 24 Submit evious Ans st A X Incorrect: Try Again; 3 attempts remaining Part C

Explanation / Answer

she catches up with you (lucky you )

means you both have travelled same distance.

x1 = x2

v1t1 = v2t2

1.1 x t1 = 1.3 x t2

Now, as she started 2min (120 sec) later

t2 = t1-120

1.1 x t1 = 1.3 (t1-120)

t1 = 780 sec

so, distance

x = v1t1 = 1.1 x 780 = 858 m
