Part 1: Vary the force applied while keeping the mass of the cart constant.→ Record the mass of the cart (include the mass of the attached force sensor).m = ______________ kg→ To vary the force applied, change the mass attached to the string. Vary the mass from20g to 300g. For each trial record the mass attached and collect data.→ Place the cart 40 cm from the motion detector (at start line). Attach a mass to the endof the string and place string over frictionless pully.→ Have your partner click start on the computer and release the cart when you hear themotion detector collecting data.→ Collect the required data and repeat procedure for new attached mass (force).→ record the force applied from the force-time graph [Remember if the trend ishorizontal to use statistics and obtain the average value.]→ record the acceleration from the velocity-time graph→ Record all data in the table provided.Part 2: Vary the mass of the cart while keeping the force applied constant.→ Calculate and record the applied force using the equation given. ( m C is the mass ofthe cart and m H is the mass attached to the string.)FT=mmC Hgm + mCHF T = ______________ N→ Vary the mass of the cart, in 100g increments, by placing masses on top of the cart.Include the initial mass of the cart in all measurements.→ Place the cart 40 cm from the motion detector (at start line). Attach a 50g mass to theend of the string and place string over frictionless pully. Place mass on top of cart.→ Have your partner click start on the computer and release the cart when you hear themotion detector collecting data.→ Collect the required data and repeat procedure for new cart mass.→ record the acceleration from the velocity-time graph→ Record all data in the table provided.For each experiment do 7-10 trials. Record the data in table provided.- 29 -
