A car traveling 93 km/h is 250 m behind a truck traveling 83 km/h . How long will it take the car to reach the truck?
A car traveling 98 km/h is 270 m behind a truck traveling 88 km/h . How long(in seconds) will it take the car to reach the truck?
A small plane mirror is mounted on a wall. A laser beam is incident on the mirror at a 45° angle, as shown in the figure. The reflected beam makes a spot on a wall 5.0 ? from, and parallel to, the wall with the mirror. When you push on the wall with the mirror, you deform the wall a little, shifting the angle of the mirror slightly and moving the spot on the other wall. If the spot moves...

An ambulance is traveling East at 20m/s. The siren emits a fixed frequency of 500Hz. Each of the following cars is traveling down the road as described. Rank the cars according to the frequency the driver will hear. Select 1 for the car which will hear the highest frequency. Remember that if the frequency is the same, select the same rank and skip the next number. I really suggest drawing a picture to help sort this out. Keep in mind...
A snowplow mounted on a truck clears a path 4 m through heavy wet snow, as shown in Figure 3.1. The snow is 0.2 m deep and its density is 160 kg/m3. The truck travels at 48 km/h. The snow is discharged from the plow at an angle of 45° from the direction of travel and 45° above the horizontal. Estimate the force required to push the plow. Neglect the friction force between the plow and the road surface, and...
A crate having a mass 50.0 kg falls horizontally off the back of the flatbed truck, which is traveling at 28 m/s. The crate slides 86.8 m on the road in coming to rest. The initial speed of the crate on the road is the same as that of the truck. (a). Draw and clearly label all of the forces acting on the crate as it slides on the road. (b). Draw the direction of the initial velocity for the...
need help. please answer #8-11 8. As an object moves away from a plane mirror on a wall and you observe the object and the image from the position of the mirror, the image of the object A. gets smaller B. may or may not get smaller, depending on where the observer is positioned. C. Is always a real image, no matter how far you are from the mirror. D. Changes from being a virtual to a real image as...
