A person takes a trip, driving with a constant speed of 91.0 km/h except for a 22.0 min rest stop. If the person's average speed is 73.4 km/h, how much time is spent on the trip and howfar does the person travel?1.8 XYour response is within 10% of the correct value. This may be due to roundoff error, or you could have a mistake in your calculation. Carry out all intermediate results to at least four-digit accuracy to minimize roundoff error. hkm

The average speed of the person can be expressed as, vavg=dtd=vavgt=73.4 km/ht

A person takes a trip, driving with a constant speed of 96.5 km/h, except for a 20.0-min rest stop. The person's average speed is 67.0 km/h. (a) How much time is spent on the trip? 1.03 Your incorrect answer may have resulted from roundoff error. Make sure you keep extra significant figures in intermediate steps of your calculation. h (b) How far does the person travel? 67.23 Your incorrect answer may have resulted from roundoff error. Make sure you keep extra significant figures in intermediate steps of your calculation. km

The "reaction time" of the average automobile driver is about 0.70 s. (The reaction time is the interval between the perception of a signal to stop and the application of the brakes.) An automobile can slow down with an acceleration of 10.6 ft/s2. 1) Compute the total distance covered in coming to a stop after a signal is observed from an initial velocity of 15.8 mi/hmi/h (in a school zone). Express your answer in feet. 2) Compute the total distance covered in coming to a stop after a signal is observed from an initial velocity of 57.4 mi/hmi/h. Express your answer in feet.

Problem 2: A car is traveling at a speed of 33 m/s. Part (a) What is its speed in kilometers per hour? Numeric : A numeric value is expected and not an expression. Skm/h = %D Part (b) Suppose the speed limit is 79 km/h. How many kilometers per hour would the car need to slow down to be going the speed limit? Numeric : A numeric value is expected and not an expression. As =
A runner travels 50 m over a duration of 12.6 s. She took 29 steps over the 50 m. What was her average step rate in steps/s? Report to two decimal points (e.g. 1.23). You are allowed a margin of error of +/- 0.02.
1.6. A vehicle takes 35 m to stop in an emergency from an initial speed of 63 km/h. One- fifth of the time elapses with the vehicle running at constant velocity before the driver reacts to the situation. Assuming constant deceleration when the brakes are applied, calculate (a) the reaction time, and (b) the distance covered during this time.
Your answer is partially correct. Raindrops fall 1.46 × 10° m from a cloud to the ground. If they were not slowed by air resistance, how fast would the drops be moving when they struck the ground? Number i Units m/s
A student drove to the university from their home and noted that the odometer reading of their car increased by 14.0 km. The straight-line distance (that is, the magnitude of displacement) between the student's home and the university is 10.0 km. This trip took 30.0 min. The student then returned home by the same path 7.00 hours after they left home. Whch of the following statement is correct? The average speed of the student during this whole day is 20.0 km/hour. The average speed of the student during this whole day is 28.0 km/hour. The average speed of the student during this whole day is 2.00 km/hour. The average speed of the student during this whole day is 0 km/hour.
