you walk from your house to a local coffee shop to get an espresso. You average  a speed of 2.4 m/s on your way there. After your espresso, you decide to run directly  back to your starting point with an average speed of 5.6 m/s. Assume you spend 4  minutes at the coffee shop. If your average speed for this entire trip is 1.9 m/s, what is  the distance between your house and the coffee shop?

An object travels 65 m west and then 80 m east in 10 minutes, what is the ratio of average speed to average velocity?

At an air show, a jet plane has velocity components vx =695km/h and vy  =415km/h  at time 4.35 s and vx =938km/h and vy =365km/h at time 7.52 s.   Please answer A,B,C,D Thank you.

A woman backs her van out of her parking space with a constant acceleration of 1.8 m/s2. Assume that her initial motion is in the positive direction. Part A: How long does it take her to reach a speed of 2.1 m/s in seconds?  Part B: If she then brakes to a stop in 0.65 s, what is her acceleration in meters per square second?

Two cars left Albany and Tenterden at the same time, passing through mount barker and both travelling at different steady speeds. The car from Tenterden completed the journey from mount barker to albany in 45 minutes at a steady pace of 64 km/h. The car from albany completed the journey from mount barker to tenterden in 20 minutes. What was the speed of the car from Albany.

What is the unit for acceleration? A race car accelerates uniformly from 18.5 m/s to 46.1 m/s in 2.47 seconds. Determine the acceleration of the car. A blue beetle starts from rest and in 4.5 seconds is flying 2.2 m/s. What is the acceleration of this insect?

An object, at time equal zero, has a velocity of 2.0 m/s and constant acceleration of 3.08 m/s². How far does it travel in 8 seconds? Do not write the units in your answer, but your answer should be in meters.

A pumpkin is shot straight up with an initial speed of 59 m/s. How long does it take to reach its maximum height, in seconds? Use g= 10 m/s2. Your answer needs to have 2 significant figures, including the negative sign in your answer if needed. (No unit is needed in your answer, it is already given in the question

A driver drove from City A to City​ B, a distance of 85 miles. She then stopped for 2 hours to see a friend in City B before continuing her journey from City B to City​ C, a distance of 225 miles. If she drove 10 miles per hour faster from City A to City B and the total time of the trip was 6 ​hours, find her average speed from City A to City B.

Jane's brother Andrew leaves home for school at 8:00 am. He walks at 4.8 kph. At 8:20 am Jane discovers that Andrew has left his homework at home. She decides to follow him on her bicycle and give him his homework, but she wants to be back home in time for an online test at 9 am. What is the minimum constant speed at which she needs to ride? (Hint: At what time of day will they meet?) Jane must ride at least kph.
