given dy= -0.75m dx= 2m g= 9.8 m/s² sol vx formula dx=vxt dx/t=vxt/t vx=dx/t solve for t form; square root of 2dy/g t= square root of 2(-0.75m)/-9.8m/s² t=0.39s vx= dx/t v= 2m/39 answer= 5.13 m/s
Given: Vox= 0.5m/s Dx= 3m g= 9.8 m/s² solve for dy Formula: dy=voy+ 1/2 gt² solve for time dx=vxt dx/vx=vxt/vx (cancel both vx) t=dx/vx t= 3m/0.5m/s formula dy=voy + t 1/2gt² dy=1/2(9.8 m/s²) (6s)² answer: -176.4 m
