The path of projectile in vacuum is a

A particle is projected under gravity (g = 9.81 m/sec²) with a velocity of 29.43 m/sec at an elevation of 30°. The time of flight in seconds to a height of 9.81 m are

From the top of a tower of height 100 m, a ball is projected with a veLocity of 10 m/sec. It takes 5 seconds to reach the ground. If g = 10 m/sec². then the angle of projection is

A particle is projected with initial velocity u making an angle a with the horizontal, its time of flight will be given by

The escape velocity for a body projected vertically upwards is 11.2 km/sec. If the body is projected in a direction making an angle of 60° with the vertical, then the escape velocity will be

A particle is projected with the speed of I rn/sec at an angle of 600 from the horizontal. The velocity of the projectile when it reaches the height of 10 m is

From the top of a hill of height 150 m, a ball is projected with a velocity of 10 m/sec. It takes 6 seconds to reach the ground. The angle of projection of the ball is

A particle is projected with a velocity of 39.2 rn/sec at an angle of 30° to the horizontal. It will move at right angle to the direction of projection after the time

Let R₁ and R₂ respectively be the maximum ranges up and down an inclined plane and R be the maximum range on the horizontal plane. Then R₁, R, R₂ are in
