Problem: In a ballistic pendulum experiment, a small marble is fired into a cup attached to the end of a pendulum. If the mass of the marble is 0.0305 kg and the mass of the pendulum is 0.250 kg,
Part A: How high will the pendulum swing if the marble has an initial speed of 5.65 m/s?
I need tutor help to solve the above question and assume that the mass of the pendulum is concentrated at its end so that linear momentum is conserved during this collision.

A .5 kg block slides along a horizontal frictionless surface at 2 m/s. It is brought to rest by compressing a very long spring of spring constant 800 N/m. The maximum spring compression is:
Vector has a magnitude of 131 units and points 32.0 ° north of west. Vector points 62.0 ° east of north. Vector points 14.0 ° west of south. These three vectors add to give a resultant vector that is zero. Using components discover the magnitudes of ..
