Question

A block is pushed against the spring with spring constant 8.5 kN/m (located on the lefthand side of the track) and compresses the spring a distance 5.3 cm from its equilibrium position. The block starts at rest, is accelerated by the compressed spring, and slides across a frictionless track . It leaves the track horizontally, ?ies throughthe air, and subsequently strikes the ground. The acceleration of gravity is 9.81 m/s^2

The speed v of the block when itleaves the track is 6.4 m/s

1. What is the horizontal distance x the blocktravels in the air?Answer in units of m

2.What is the total speed of the block when ithits the ground?Answer in units of m/s

Explanation / Answer

A) 7,72 m/sec B) 3.5 m c) and V= 8.46 m/sec
