A car $P$ moves due east with a speed $10 \mathrm{m} {\mathrm{s}}^{–1}$ and another car $Q$ moves due west with a speed $15 \mathrm{m} {\mathrm{s}}^{–1}.$ The velocity of car $P$ as observed by car $Q$ is

A car $P$ moves due east with a speed $10 \mathrm{m} {\mathrm{s}}^{–1}$ and another car $Q$ moves due west with a speed $15 \mathrm{m} {\mathrm{s}}^{–1}.$ the velocity of car $Q$ as observed by car $P$ is

A car $\mathrm{P}$ moves due east with a speed $10 {\mathrm{ms}}^{-1}$ and another car $\mathrm{Q}$ moves due west with a speed $15 {\mathrm{ms}}^{-1}$. If at the moment $\mathrm{t}=0,$ the separation between the cars is $90 \mathrm{m}$ and the length of each car is $5 \mathrm{m},$ the moment of time at which they completely cross each other is $\mathrm{t}=$

A car $\mathrm{P}$ moves due east with a speed $10 {\mathrm{ms}}^{-1}$ and another car $\mathrm{Q}$ moves due west with a speed $15 {\mathrm{ms}}^{-1}$. If at the moment $\mathrm{t}=0,$ the separation between the cars is $100 \mathrm{m},$ the separation between them at the moment $\mathrm{t}=2 \mathrm{s}$ can be

Two cars $\mathrm{A}$ and $\mathrm{B}$ cross a point $\mathrm{P}$ simultaneously with velocities $10{ \mathrm{ms}}^{-1}$ and $15{ \mathrm{ms}}^{-1}.$ After that they move with different uniform accelerations and the car $\mathrm{A}$ overtakes $\mathrm{B}$ with a speed of $25{ \mathrm{ms}}^{-1}.$ What is velocity of $\mathrm{B}$ at that instant?

A ball is thrown vertically upwards with a velocity $\mathrm{u}$ with respect to ground from the balloon descending with velocity $\mathrm{v}.$ The ball will pass by the balloon after time
