JEE Main 2024 — Motion In Two Dimensions Question with Solution

JEE Main 2024 (30 Jan Shift 2)

Question

Projectiles A and B are thrown at angles of 45° and 60° with vertical respectively from top of a 400 m high tower. If their times of flight are same, the ratio of their speeds of projection vA:vB is:

Correct answer
D1:2

Step-by-step explanation

For same time of flight, vertical component of velocity of projection must be same. Therefore,

vAsin45°=vBsin30°⇒vAvB=1212⇒vAvB=12
