PHXI04:MOTION IN A PLANE

361969 The speed of a projectile when it is at its greatest height is \(\sqrt {2/5} \) times its speed at half the maximum height. The angle of projection with horizontal is

1 \(30^\circ \)
2 \(60^\circ \)
3 \(45^\circ \)
4 \(15^\circ \)
PHXI04:MOTION IN A PLANE

361970 Assertion :
Two particles of different mass, projected with same velocity, the maximum height attained by both the particle will be same.
Reason :
The maximum height of projectile is independent of particle mass.

1 Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.
2 Both Assertion and Reason are correct but Reason is not the correct explanation of the Assertion.
3 Assertion is correct but Reason is incorrect.
4 Assertion is incorrect but reason is correct.
PHXI04:MOTION IN A PLANE

361971 The trajectory of a projectile in a vertical plane is \(y = ax - b{x^2}\), where \(a\) and \(b\) are constants and \(x\) and \(y\) are respectively horizontal and vertical distances of the projectile from the point of projection. The maximum height attained by the particle is

1 \(\frac{{{a^2}}}{b}\)
2 \(\frac{{{b^2}}}{{2a}}\)
3 \(\frac{{2{a^2}}}{b}\)
4 \(\frac{{{a^2}}}{{4b}}\)
PHXI04:MOTION IN A PLANE

361972 At the maximum height of a projectile, the velocity and acceleration are

1 Parallel to each other
2 Antiparallel to each other
3 Perpendicular to each other
4 Inclined to each other at \(45^\circ \)
