Question

Raindrops are falling vertically with a velocity of 10 m/s. To a cyclist moving on a straight road the raindrops appear to be coming with a velocity of 20 m/s. The velocity of cyclist is: (A) 10 m/s (B) 10 √3 m/s (C) 20 m/s (D) 20√3 m/s

By using addition of vector in vector form <img class="img-fluid question-image" alt="image" src="https://cdn.tardigrade.in/img/question/physics/fc1fc477ab1113a61f1afbf49e28ca6a-.png" /> Vm =√(20)2-(10)2 =√400-100 =√300

Q. Raindrops are falling vertically with a velocity of $10 m / s$ . To a cyclist moving on a straight road the raindrops appear to be coming with a velocity of $20 m / s$ . The velocity of cyclist is:

$10 m / s$

$103 m / s$

$20 m / s$

$203 m / s$

By using addition of vector in vector form

$V_{m} = (20)^{2} - (10)^{2}$
$= 400 - 100$
$= 300$
