To maintain a constant speed, the force provided by a car’s engine must equal the drag force plus the force of friction of the road (the rolling resistance). (a) what are the magnitudes of drag forces at 70 km/h and 100 km/h for a toyota camry? (drag area is 0.70 m2 ) (b) what is the magnitude of drag force at 70 km/h and 100 km/h for a hummer h2? (drag area is 2.44 m2 ) assume all values are accurate to three significant digits.

What is the average speed of a car that travels 40mph for 1 hour and 60 mph in another hour will mark brainliest

Asatellite component is in the shape of a cube with 10cm edges, has an evenly distributed mass of 2 kg and one bolt hole at each of four corners. if the maximum predicted random vibration environment is 10 grms, what bolt size would be a good choice for restraint? what other factors might drive bolt size besides force/stress?

Visualize the problem and identify special cases first examine the problem by drawing a picture and visualizing the motion. apply newton's 2nd law, ∑f⃗ =ma⃗ , to each body in your mind. don't worry about which quantities are given. think about the forces on each body: how are these consistent with the direction of the acceleration for that body? can you think of any special cases that you can solve quickly now and use to test your understanding later? one special case in this problem is if m2=0, in which case block 1 would simply fall freely under the acceleration of gravity: a⃗ 1=−gj^.
