1.A mechanic jacks up a car to an angle of 7.0° to change the front tires. The car is 2.90 m long and has a mass of 1180 kg. Its center of mass is located 1.12 m from the front end. The rear wheels are 0.40 m from the back end. Calculate the torque exerted by the car around the back wheels.(adsbygoogle = window.adsbygoogle || []).push({});

2.Torque=Fd(sin feta)

F=mg

3.d=2.9m-1.12m-.4m

= 1.38m

F=1180kg(9.8m/s^2)=11564N

T=11564N(1.38m)sin (7)

Is this correct?
