11 Physics Ch-3: Motion in a Plane

The range of a particle is R when the angle of projection is 60⁰. For the same velocity of projection and same range, the other possible angle of projection is:

At 45⁰ of projection angle to the horizontal, the maximum height H and horizontal range R are related as:

A particle moves in the xy-plane from position (2m, 4m) to (6m, 8m) in 2 s. Magnitude and direction of average velocity is

The position vector of an object at any time t is given by (3t² î + 6 ĵ + tk̂) m/s. Its velocity along y-axis at t = 2 s has the magnitude

The path of the projectile is parabola. The path for the same projection velocity and projection angle depends upon

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 =-1m, its velocity is (2 m/s)(- ĵ). What is the object's acceleration when it is y = 2 m?

What will be the radial and tangential acceleration of a body in uniform circular motion?

What will be the ratio between maximum range and square of time of flight in projectile motion for the same initial velocity?

The path of a projectile thrown with some acute angle (not vertically up) from horizontal will have the path

What will be the compnent of vector A =î along vector B = – ĵ ?

A projectile is thrown with same initial velocity vector u and same projection angle (θ) from horizontal ground. How will therange and maximum height be related?

Which one remains constant in projectile thrown from horizontal ground?

The horizontal acceleration in projetile motion from ground is

The time of flight is given by

The maximum value of range of a projectile thrown from horizontal ground is

At the projection angle 45⁰, the maximum height of a projectile thrown from ground is

If the initial velocity is vector u = (3î + 4ĵ) m/s, then time of flight in a projectile motion trown horizontally is:(take g = 10 m/s²)

If the initial velocity vector u = (3î + 4ĵ) m/s, then after falling the particle, the velocity is

In the uniform circular motion, tangential acceleration is

In the uniform circular motion, if angular acceleration is parallel to angular velocty, the speed
