The mass of a sports car is 1000 kg. the shape of the car is such that the aerodynamic drag coefficient is 0.260 and the frontal area is 2.10 m2. neglecting all other sources of friction, calculate the initial acceleration of the car, if it has been traveling at 90 km/h and is now shifted into neutral and is allowed to coast. (take the density of air to be 1.295 kg/m3.)

Which of the following are appropriate acceleration units?

The bar of prob. 5/82 is repeated here. the ends of the 0.4-m bar remain in contact with their re- spective support surfaces. end b has a velocity of 0.5 m/s and an acceleration of 0.3 m/s2 in the di- rections shown. determine the angular accelera- tion of the bar and the acceleration of end a.

Amass attached to a spring is displaced from its equilibrium position by 5cm and released. the system then oscillates in simple harmonic motion with a period of 1s. if that same mass–spring system is displaced from equilibrium by 10cm instead, what will its period be in this case? a mass attached to a spring is displaced from its equilibrium position by and released. the system then oscillates in simple harmonic motion with a period of . if that same mass–spring system is displaced from equilibrium by instead, what will its period be in this case? a) 0.5sb) 2sc) 1sd) 1.4s
