Final answer:
Without specific details, it is not possible to accurately answer the initial question. General driving experience suggests a right turn can take 2-3 seconds, and accelerating to 30 mph could take approximately 4-6 seconds. For specific physics problems, formulas such as = v/a and deceleration = -v/t can be used to calculate time and deceleration.
Step-by-step explanation:
The question on how long it takes to turn right and accelerate to 30 mph seems to be lacking context, such as initial speed or the rate of acceleration. However, I can provide an explanation based on general driving experiences and physics principles. In normal driving conditions, a right turn typically takes about 2-3 seconds assuming it is executed safely within a residential area. Accelerating from a stop to 30 mph could take approximately 4-6 seconds, depending on the vehicle's acceleration capabilities. It's key to note that the overall time to execute a combination of actions (such as a turn and then an acceleration) will vary based on specific driving factors and should be done with safety as a priority.
To answer sample question 18 regarding acceleration: (a) To calculate the time it takes to reach a speed of 2.00 m/s with an acceleration of 1.40 m/s2, you would use the formula t = v/a, where t is time, v is velocity, and a is acceleration. (b) For deceleration, if the commuter brakes to a stop in 0.800 s, the deceleration would be calculated as the change in velocity over the time, which is deceleration = -v/t, where v is the initial speed before braking.
