After one second the velocity of a projectile makes an angle of 45^∘ with the horizontal. After another one more second its is travelling horizontally. The magnitude of its initial velocity and angle of projectile are (g=10m/s^2)

A particle is projected from the ground with an initial velocity of 20m/s at an angle of 30∘ with horizontal. The magnitude of change in velocity in a time interval from t=0 to t=0.5s (g=10m/s^2)
