Two particles are projected with the same initial velocity, one makes an angle θ with the horizontal while the other makes an angle θ with the vertical. If their common range is R, then the product of their time of flight is directly proportional to:
1. R
2.
3.
4.
If two projectiles, with the same masses and with the same velocities, are thrown at an angle \(60^\circ\) & \(30^\circ\) with the horizontal, then which of the following quantities will remain the same?
1. | time of flight |
2. | horizontal range of projectile |
3. | maximum height acquired |
4. | all of the above |
A particle is projected, making an angle of \(45^{\circ}\)
1. \(\frac{K}{\sqrt{2}}\)
2. \(\frac{K}{2}\)
3. \(2K\)
4. \(K\)
A particle (A) is dropped from a height and another particle (B) is projected in a horizontal direction with a speed of 5 m/s from the same height. The correct statement, from the following, is:
1. | Particle (A) will reach the ground first with respect to particle (B) |
2. | Particle (B) will reach the ground first with respect to particle (A) |
3. | Both particles will reach the ground at the same time |
4. | Both particles will reach the ground at the same speed |
