Bidirectional jerk motion on a stopping vehicle?
A stopping vehicle (say a car) has an apparent retardation (which may/may not be constant in magnitude) when force via brakes is applied. I travel by subway trains, and I noticed an odd... more
If a hockey puck slides on a perfectly frictionless surface, it will eventually slow down because of its inertia.
Rotational physics problem
a 1.5kg uniform rod of length .75 meters swings from rest around an axis through its end through an angle of 60 degrees. It strikes the center of a small .25 kg ball which sits on the edge of a... more
Inertia Centre Of Mass
momemt of inertia
We have to find moment of inertia of a semi circular disc whose axis of rotation is passing through the centre making an angle k with the diameter and lying in the plane of disc .
A boat starts straight across a river at 35 km/hr. The current pushes the boat downstream at 3.50 km/hr. What is the resultant velocity of the boat?
Test tomorrow and I'm not sure on how to work out the equations, especially velocity. Any help would be appreciated. Thanks!
Physics: What is her momentum of Inertia?
A figure skater can increase her angular velocity from a speed of 2.00 revolutions in 3.00 seconds to 5.00 revolutions in 2.00 seconds by bringing her arms in. If her moment of inertia was 4.60 kg... more
