361933 Projectiles \(A\) and \(B\) are thrown at angles of \(45^{\circ}\) and \(60^{\circ}\) with vertical respectively from top of a \(400\,\,m\) high tower. If their ranges and times of flight are same, the ratio of their speeds of projection \(v_{A}: v_{B}\) is [Take \(g = 10\;m{s^{ - 2}}\) ]

361934 A body is projected horizontally with a velocity of 4 \(m\)/\(s\) from the top of the high tower. The velocity of the body after 0.7 \(s\) is nearly \(\left( {{\rm{take}}\;g = 10\;m/{s^2}} \right)\)

361935 A number of bullets are fired horizontally with different velocities from the top of a tower then they reach the ground

361936 Assertion :
When a body is dropped or thrown horizontally from the same height, it would reach the ground at the same time.
Reason :
Horizontal velocity has no effect on the vertical motion.
