Help with this question

  1. Mar 31, 2004 #1
    I have a really difficult question i need help on.

    A 1.9-kg block slides down a frictionless ramp. Ths top of the ramp is 1.5-m above the ground; the bottom of the ramp is 0.25-m above the ground. The block leaves the ramp moving horizontally, and lands a horizontal distance 'd' away. Find the distance 'd'.

    Oh and the ramp is curved so the block slides horizontally when it leaves the ramp.

    Help please!

    First find the speed of the block as it leaves the slide. Use conservation of energy.

    Then apply the usual kinematic equations for projectile motion: the y-direction has an acceleration due to gravity; the x-direction is constant speed motion. Note that the initial velocity as it leaves the slide is purely horizontal.
