1.

a particle projected from ground moves at angle 45 degree with horizontal one second after projection and speed is minimum two seconds after the projection the angle of projection of particle is ( neglect the effect of air redistance)

Answer» HELLO Dear________✌️✌️


speed is minimum after 2 SEC means speed=vcos theta
after 1 second
v'cos45=vcos theta
also
v'sin45-g*1=0
=>v'sin45=g
=>v'=gsqrt2
also
vsin theta-g*1=v'sin45=g
=>vsin theta=2g
=>TAN theta=2g/v'cos45=2
