A railroad flatcar is traveling to the right at a speed of `13.0 ms^(-1)` relative to an observer standing on the groun . Someone is riding a scooter on the flatcar. Corresponding to the relative velocities `18 m s^(-1)` to the right, `3 m s^(-1)` to the left and `0 ms^(-1)` of scooter w.r.t. ground, find thefrlative velocities (magnitude and direction) of scootre w.r.t. the flatcat.

Text Solution

Verified by Experts

a. `v_(as) =18 ms^(-1) v_(c) =13 ms^(-1)`
`v_(s//c) =v_(s)-v_(c) =18-13 =5 ms^(-1)`
b. `v_(s) =-3 ms^(-1) v_(s//c) =v_(s)-v_(c) =-3 -13 =-16 ms^(-1)`
`v_(s) =0 v_((s)/(c)) =v_(s)-v_(c) =0-13 =-134 ms^(-1)`.
Negative sign indicates left direction.
