A200-g block is pressed against a spring of force constant 1.40 kn/m until the block compresses the spring 10.0 cm. the spring rests at the bottom of a ramp inclined at 60° above the horizontal. determine how far up the incline the block moves from its initial position before it stops if the coefficient of kinetic friction is 0.400.

Aparticle initially located at the origin has an acceleration of = 2.00ĵ m/s2 and an initial velocity of i = 8.00î m/s. find (a) the vector position of the particle at any time t (where t is measured in seconds), (b) the velocity of the particle at any time t, (c) the position of the particle at t = 7.00 s, and (d) the speed of the particle at t = 7.00
