The range of a particle is R when the angle of projection is 40⁰. For the same velocity and projection and range, the other possible angle of projection is:
2.
For an object thrown at 45⁰ to the horizontal, the maximum height H and horizontal range R are related as:
3.
A particle moves in the xy-plane from position (2m, 4m) to (6m, 8m) in 2 s. Magnitude and direction of average velocity is
4.
The position vector of an object at any time t is given by 3t² î + 6t ĵ + k̂. Its velocity along y-axis has the magnitude
6.
An object moves at a constant speed along a circular path in a horizontal x-y plane, with the centre at the origin. When the object is at x =-2m, its velocity is (4m/s)(- ĵ). What is the object's acceleration when it is y = 2 m?
7.
If a(r) and a(t) represent radial and tangential acceleration, the motion of a particle will be uniformly circular if
8.
Ratio between maximum range and square of time of flight in projectile motion is
9.
A particle moves in a plane with constant acceleration in a direction different from initial velocity. The path of the particle will be
