Speed And Velocity

A projectile is thrown with an initial velocity xî+yj from the ground. The range of the projectile is twice the maximum height of the projectile. The value of is is

A body initially at rest is moving with uniform acceleration 'a'. Its velocity after 'n' seconds is 'v'. The displacement of the body in last 2 seconds is

Let and represent the positions of particles P and respectively as function of time t. The relative speed of the two particles at the instant t = 1 sec will be [consider and are in metres and t is in seconds]

Five molecules of an ideal gas have velocities 2, 3, 4, 4 and 5 m/s. If their average velocity is and their RMS velocity is then

A thin uniform rod of length L and mass M is swinging freely about a horizontal axis passing through its end. Its maximum angular speed is ω. Its centre of mass rises to a maximum height of

The velocity of a particle as a function of time t is given by . The dimension of is

An artificial satellite is moving in a circular orbit around the earth with a speed equal to half the magnitude of the escape velocity from the earth's surface. The height of the satellite above the earth's surface is [R = Radius of the earth]
