An aeroplane is flying at a constant horizontal velocity of \(600\ \text{km/hr}\) at an elevation of \(6\ \text{km}\) towards a point directly above the target on the Earth's surface. At an appropriate time, the pilot releases a ball so that it strikes the target at the Earth's surface. The ball will appear to be falling:

1. On a parabolic path as seen by the pilot in the plane

2. Vertically along a straight path as seen by an observer on the ground near the target

3. On a parabolic path as seen by an observer on the ground near the target

4. On a zig-zag path as seen by the pilot in the plane

A bomb is dropped from an aeroplane moving horizontally at constant speed. When air resistance is taken into consideration, the bomb:

1. Falls to earth exactly below the aeroplane

2. Fall to earth behind the aeroplane

3. Falls to earth ahead of the aeroplane

4. Flies with the aeroplane

An aeroplane is flying horizontally with a velocity \( u = 600\ \text{km/h}\) at a height of \(1960\ \text{m}\). When it is vertically at a point \(A\) on the ground, a bomb is released from it. The bomb strikes the ground at point \(B\). The distance \(AB\) is:

1. \(1200\ \text{m}\)

2. \(0.33\ \text{km}\)

3. \(3.33\ \text{km}\)

4.  \(33\ \text{km}\)

An aeroplane moving horizontally with a speed of \(720\ \text{km/h}\) drops a food packet while flying at a height of \(396.9\ \text{m}\). The time taken by a food packet to reach the ground and its horizontal range is:

1. \(3\ \text{s}\ \text{and}\ 2000\ \text{m}\)

2. \(5\ \text{s}\ \text{and}\ 500\ \text{m}\)

3. \(8\ \text{s}\ \text{and}\ 1500\ \text{m}\)

4. \(9\ \text{s}\ \text{and}\ 1800\ \text{m}\)

A particle \((A)\) is dropped from a height and another particle \((B)\) is thrown in the horizontal direction with a speed of \(5\ \text{m/s}\) from the same height. The correct statement is:

1. Both particles will reach at ground simultaneously

2. Both particles will reach at ground with same speed

3. Particle (A) will reach at ground first with respect to particle \((B)\)

4. Particle (B) will reach at ground first with respect to particle \((A)\)

A bomber plane moves horizontally with a speed of \(500~\text{m/s}\) and a bomb is released from it. The bomb strikes the ground in \(10~\text{s}\). The angle at which it strikes the ground will be: \((g= 10~\text{m/s}^2)\)
1. \(\tan ^{-1}\left(\frac{1}{5}\right )\)
2. \(\tan \left(\frac{1}{5}\right)\)
3. \(\tan ^{-1}(1)\)
4. \(\tan ^{-1}(5)\)

A projectile is fired with initial velocity \(u\) at some angle \(θ\) has a range \(R\). If the initial velocity is doubled at the same angle of projection, then the range will be:

1. \(2 R\)

2. \(R/2\)

3.  \(R\)

4. \(4 R\)

If the initial velocity of a projectile is doubled, keeping the angle of projection the same, the maximum height reached by it will:

1. Remain the same

2. Be doubled

3. Be quadrupled

4. Be halved

In the motion of a projectile under gravity, its:

1. Total energy is conserved

2. Momentum is conserved

3. Energy and momentum are both conserved

4. None is conserved

The range of a projectile for a given initial velocity is maximum when the angle of projection is \(45^°\). The range will be minimum if the angle of projection is:

1. \(90^°\)

2. \(180^°\)

3. \(60^°\)

4. \(75^°\)
