Based on the time measurements in the table, what can be said about the speed of the car on the lover
track as compared to the higher track?
Distance
traveled
(m)
Lowertrack Higher track
elapsed time elapsed time
(S)
(S)
How can the reasoning for the above answer be best
explained? On the higher track, the elapsed time is
6 01
Calculate speeds for each track. How much faster was
the car on the higher track than the lower track?

3. a worker pushes a 30.5 kg polished stone along a polished table with a force on bonin a straight line for 5.20 s after starting from rest. there is no friction between thestone and the table. at the end of the table. the stone is hooked to a cable with a lengthof 62.0 cm to rotate it to a rough table to store until they can be picked up. the roughtable has a coefficient of static friction 0.702 with the polished stone. remember that 8= 9.80 m/s2a) what is the speed of the stone when it is hooked to the cable? b) what is the tension in the cable while the stone is rotating? (there is still nofriction)c) how much force is needed to make the stone begin sliding from rest on therough table? ius = 0.70262.0 cm30.5 kg20.5 kg6= 0
