Karen is driving on the 210 freeway in her 3,500 kg Escalade when she sees Hayley driving a Tesla on the street next to the freeway. Karen immediately h the off ramp, which has a radius of curvature of 35 m, so she could catch her. If the coefficient of friction between the road and Karen's tires is 0.8, what is fastest speed Karen can travel and safely make the turn? O 10.4 m/s O 16.6 m/s 26.3 m/s O 30.2 m/s

Paige still wants to steal Esmeralda's 221 pound (100.2 kg) box of red vines. After going to Esmeralda's and convincing her to watch Princess Switch 3 (Romancing
the Star) on Netflix, Paige waits until Esmeralda steps out the room to get more napkins (it's a tear jerker) before making her move. Paige's been working out, so she's
able to push the box outside of Esmeralda's house and to her car with ease. But now she has to get into her trunk. Paige sets up a 60 degree ramp, and pushes the
box up the ramp with a force of 1,500 N. If the coefficient of friction between the box and the ramp is 0.7, what will be the acceleration of Esmeralda's box of red
vines?
O 3.1 m/s^2
1.8 m/s^2
0.4 m/s^2
O 6.3 m/s^2

Expert Solution
Step 1

This is a problem of motion in a circular curve. In this case, Karen's tires must exert a frictional force on the surface of the road in order to provide the required centripetal force for the safe negotiation of the curve.
