varying force practical

• clamp pulley to end of desk
• attach string to trolley and place over pulley
• attatch mass holder to string
• place mass on mass holder
• use w=mg to get force
• measure distance between starting point of trolley to edge of desk
• measure the distance with a ruler
• pull the pulley off the desk and time how long it takes for the trolley to get from starting to end point with timer
• do v=s/t
• repeat for different masses
