Ball A (m 0.5 kg, I 0.7 MR2) is held at rest against a spring, compressed by a distance x-40 cm. The ball is released and move along a frictionless surface (Ho 4 m) until it collides with ball B (m- 0.25 kg, I- 0.5 MR2) which is at rest. After the collision, the two balls roll down a track (which has friction!) and leaves the track at a height, H,- 1m. Ball B goes to a height of HB-5m...

A slender, uniform metal rod of mass M and length l is pivoted
without friction about an axis through its midpoint and
perpendicular to the rod. A horizontal spring, assumed massless and
with force constant k, is attached to the lower end of the rod,
with the other end of the spring attached to a rigid support.
(Figure 1)

enough that the spring remains effectively horizontal...

A ball is kicked from a location < 6, 0, -9> m (on the ground) with initial velocity<-13, 17.0, -4> m/s. The ball's speed is low enough that air resistance is negligible (a) What is the velocity of the ball 0.6 s after being kicked? (Use the Momentum Principle!) 11.2 4 m/S (b) In this situation (constant force), which velocity will give the most accurate value for the location of the ball 0.6 s after it is kicked? the arithmetic...

Two metal rods, vertically placed and separated, are joined at
the top.
a distance of l = 50cm. The whole, whose resistance is
considered contempt-
It is placed within a uniform magnetic field of flow density B
= 0.01kT perpendicular to the plane defined by the rods. By them,
it slides downwards with constant speed of v = 1jm / s, without
friction and without interrupting the contact, a bar AB whose mass
is m = 1g. Determine the resistance...
