A new car is tested on a 270-m-diameter track. Part A If the car speeds up at a steady 1.2 m/s², how long after starting is the magnitude of its centripetal acceleration equal to the tangential acceleration? Express your answer with the appropriate units. At = Submit μÅ Value Request Answer Units
Help! An asteroid is heading towards us at 10 km/s. Scientists decide the best solution is to attach a rocket to the asteroid and fire it to change the trajectory of the asteroid. If the rocket is fired for 8 min, the scientists calculate that the new speed for the asteroid will be 21 km/s and its new trajectory will be at an angle of 25° to its original path. Part A In the process described above, what is the acceleration of the asteroid? Express your answers using two significant figures separated by a comma. Assume that the positive axis is in the direction of the initial motion of the asteroid. The final motion of the asteroid has components in the x and positive y directions only. ax ay = for Part A for Part A undo for Part A redo for Part A reset for Part A keyboard shortcuts for Part A help for Part A Review I Constants m/s2

Bumblebees are skilled aerialists, able to fly with confidence around and through the leaves and stems of plants. In one test of bumblebee aerial navigation, bees in level flight flew at a constant 0.40 m/s, turning right and left as they navigated an obstacle-filled track. While turning, the bees maintained a reasonably constant centripetal acceleration of 4.0 m/s. Part A What is the radius of curvature for such a turn? .2 Express your answer with the appropriate units.

a The diagram above shows a yellow car going around a curve in a road (the broad gray line with a white dashed line) as seen from above. In the diagram, the car is moving to the right and slightly upward (notice the headlights are to the right and the tail lights are to the left). At its position shown in the diagram, the road has a radius of curvature r of 43 meters. At the time shown in the diagram, the car is speeding up at a rate of 2.2 m/s?. Also at this time, the total acceleration of the car (shown by a green arrow in the diagram) has a magnitude of 4.2 m/s?. Calculate the speed of the car, in units of meters per second, and this time. .-----
