3 (Start on a new page.) A stone is thrown vertically upward at a velocity of 10 m·s-1 from the top of a tower of height 50 m. After some time the stone passes the edge of the tower and strikes the ground below the tower. Ignore the effects of friction. 3.1 Draw a labelled free-body diagram showing the force(s) acting on the stone during its motion.(1) 3.2 Calculate the: 3.2.1 Time taken by the stone to reach its

with a stationary block of mass M. Assuming a fully elastic collision find the distance the block will slide if the dynamic friction is µ. during swing down m acquires speed u: m g Δh = 1/2 m u2 ⇒ u = [2g R(1 - cosθ)]1/2 let ρ = (m/M) then speed of block just after impact is: V = 2ρ2 u/(1 + ρ) v = u (ρ - 1)/(1 + ρ) so after collision‚ block M has KE: K = 1/2 M V2 friction force does work on the sliding block to bring its speed to zero: W = f Δx = µ M g Δx = K ⇒ Δx = K/(µ M g) = 1 /2 V 2/(µ

Lang‚ Member‚ IEEE‚ and Pradnya Nagarkar Abstract-This paper presents a detailed discussion of micromotor fabrication and related critical issues. The micromotors under study are of the variable-capacitance side-drive type with salient-pole and wobble (harmonic) designs. Polysilicon surface micromachining forms the basis of the
