A block starts at rest and slides down a friction-less trackexpectfor a small rough area on a horizontal section of the track(asshown in the figure below).http://i41.tinypic.com/1zozqps.jpgIt leaves the track horizontally, flies through the air,andsubsequently strikes the ground. The acceleration of gravityis9.8m/s2.A) What is the speed 'v' of the block as it leaves the track?Answerin units of m/s?B) What is the horizontal distance 'x' the block travels throughtheair? Answer in units of m.C) What is the total speed of the block as it hits theground?Answer in units of m/s.
A block is pushed against the spring with spring constant k(located on the left-hand side of the track) and compresses thespring a distance 5.4 cm from its equilibrium posistion (as shown).What is the total speed of the block when it hits the ground?Answer in units of m/s.
A block starts at rest and slides down a frictionless track. Theacceleration of gravity is 9.81 m/s^2. It leaves the trackhorizontally, striking the ground 4.6 m from the end of the track.(the track's horizontal bend is 2.1 m high off the ground) theblock weighs 423 gAt what height off the ground is the block released? I found V0 tobe 7.02 m/s
