Question

A block of mass 1.0kg is held by a spring compressed a distance x=0.2m from it's equilibrium position. The spring constant, k of the spring is 5000.0N/m. When the mass is let go from ground level the block moves up the frictionless slope to reach point B where the slope gives way to a horizontal surface. (a) use the energy conservation principle to determine the velocity of the block at point B. (b) determine the range BC of the projectile motion. (c) determine the compression length on the spring needed such that the block just reaches the point D before heading back down the slope.

Explanation / Answer

a.).5K*X^2=.5M*V^2 +Mgh (h= distance traveeld on slope into sine of incline angle) velocity is equal to 31.62m/s(here as the incline angle is not given taking it to be zero)

b.)Range is 100Sin(2X) where x is the angle of the incline

c.).5X^2=Mgh (h= distance traveeld on slope into sine of incline angle)

here the incline angle isnot given either the distance traveeled by blick is also not given with this we cannot say the xact ans

M is the mass of block
