Question asked by: Lisaseote - 2 years ago

Ik geef je een probleem en ik wil dat je het oplost terwijl je het me stap voor stap uitlegt. Dit is het probleem: Een doos glijdt omlaag over een spiraalvormige helling die gedefinieerd kan worden door r=0,3 m, =0,7t3 rad en z=2-0,2t2 m. Hierin is t de tijd uitgedrukt in seconden. Bepaal de grootte van de versnelling van de doos op het moment dat =2 rad. Rond af tot op 2 decimalen.


Tip: bereken eerst het tijdstip in seconden waarop je de grootte van de versnelling wil weten.

Leg alle stappen goed uit De uitleg moet geschreven zijn op het niveau van de Universiteit.
