... A block S (the sliding block) with mass M =3.3 kg is free to move along a horizontal frictionless surface. It is connected by a cord that wraps over a frictionless pulley, to a second block H (the hanging block) with mass m = 2.1 kg. The cord and pulley are considered to be “massless”. The hanging b ...

... (10) Imagine that our sun ran out of nuclear fuel and collapsed. What would its radius have to be in order for its period of rotation to be the same as “pulsars” with a rotational period of 1.33 seconds/rotation? The sun’s current period of rotation is 25 days. (I = 2/5mR2 for spheres). Msun = 2.0 x ...

AIM: Force and Motion Ideas An object`s position can be described
... Some types of force, typically those caused by everyday pushes and pulls (such as when people push or pull on other objects), only exist when the objects involved are in direct contact with each other. When contact is broken these forces no longer exist. Some types of force, such as gravity and m ...
