Chapter 36: Q. 3 (page 1058)

Firecracker A is 300m from you. Firecracker B is 600m from you in the same direction. You see both explode at the same time. Define event 1 to be 鈥渇irecracker A explodes鈥� and event 2 to be 鈥渇irecracker B explodes.鈥� Does event 1 occur before, after, or at the same time as event 2? Explain.

Short Answer

Expert verified

Event 1 will occur after event 2.

Step by step solution

01

Given information

We have given,

Firecracker A distance =300m

Firecracker B distance =600m

We have to find the which event will occur first.

02

Simplify

As the distance from the firecracker A is less then the firecracker B.

DistanceA<DistanceB

Since speed are same for both the firecracker to observe to me.

So we can say that the time for the event A to observe will be fast then the event B.
