You are organizing a soap box derby on the slopes of Mount Trashmore. To
get approval from Parks and
Recreation, you are required to
provide proof that the cars will not
exceed a speed of 10 m/s. You
establish a research team to
construct a track and race car to
determine the maximum vertical
height the cars can begin the race
without exceeding 10 m/s at the finish
line. You will then use the data from
the research to obtain permits from
Parks and Recreation to hold the
event.

A33.1 g copper object is launched from a 1.5 m 30° steel incline positioned on the floor by being pulled up a string attached to a 50.0 g mass suspended vertically over a pulley. the object is projected towards a glass table where it lands when it is at the point along its trajectory with the lowest speed. it comes to a halt when it clears the opposite edge of the table. it then falls and lands on 9 physics texts each 5 cm thick that are stacked on the floor on the opposite side of the table. assume that the table does not have a ledge and the rectangular object experiences 0.05 n of air resistance as it falls towards the books. how far and how long did the object travel and how fast does it hit the books. assume that at the moment the copper object leaves the incline, the massless string and ideal pulley break off

Abanked road comer of radius 146 m is to be constructed. if the comer is designed for vehicles moving with a speed of 20.0 m/s, what should the banking angle be, in units of degrees?

One object has a mass of 1 kg and another object has a mass of 3 kg. if the speeds are the same, which of the following is true about their kinetic energy?
