1. What is the acceleration of a car if it starts from rest and accelerates uniformly over a time of 2.2 seconds for a distance of 30m ?
Step by step
Solved in 2 steps
- Solve the following problems using the GRESA format. 1. A car accelerates from 13m/s to 25m/s in 6.0 sec. What is its acceleration? How far did it travel in this time? 2. How long does it take for a rock to fall from a 15.50 m high building? What is its final velocity?You decide to flip a coin to determine whether to do your physics or English homework first.The coin is flipped straight up. (a) If the coin reaches a high point of 0.25 m above where youreleased it, what was its initial speed? (b) If you catch it at the same height as you released it,how much time did it spend in the air? Hint: The time it takes the ball to rise equals the time ittakes to fall.By US law , vehicle speedometers are supposed to be accurate to with+\-2.5% . If a car speedometer read 40mph what is the fastest speed the car could be moving ? The slowest? Show your work and briefly explain how you did this in several bullets

A horse travels 65 km/hr with a distance of 5.98 km . a. How long does the horse travels? b. What is the new speed of the horse if he travels twice his time travelled? Velocity 1. It is 21,000 kilometers around the earth and the earth rotates in 24 hrs. How fast is it rotating? 2. Jessica jogs on a path that is 25 kilometers long to get to a park that is south of the jogging path. If it takes Jessica 2.5 hours then, what is the velocity? 3. How long will it take light moving at 300,000 km/s to reach us from the sun? The sun is 150,000,000 km from earth. 4. An auto travels going to Roxas City at a rate of 25 km/hr for 0.045 hour , then at 50 km/hr for 0.056 hr, and finally at 20 km/hr for 0.015 hour. Find the total…I wonder if you can't assist me with this problem. I see that we're being asked to find V_o, but in order to solve, we need to calculate the time and the acceleration. We have the means to solve for acceleration using the second set of data values, then plug that value in to find time. But i'm a bit lost after that. Attached are photts of the question and my work.

In answering these problems, apply appropriate formulae, principles, and equations What is the instantaneous velocity of a freely falling object 10 seconds after it is released from a position of rest? What is the average velocity during this 10 second time interval? How far will it fall during this time?
- A car accelerates from rest at 4 m/s2. What is the velocity of the car after 4 seconds? What is the distance travelled by the car in 3 seconds?An airplane takes off from rest. It accelerates 4 m/s2 for 35 seconds. What is its velocity at the end of the acceleration? How far did it go in the 35 seconds?Using what's given below, answer the following parts for practice: Ansdrew needs to get produce from the store, which is a distance d=2.87 km east of his condo. Andrew rides his bicycle to the store at a constant speed of v1= 6.19 m/s, and rides back to his condoat the slower speed of v2=2.22 m/s. The figure below is not drawn to scale. Part A: How long, in seconds, does it take for Andrew to reach the store? And how long in both seconds and minutes does the whole trip take? Part B: What total distance, in kilometers, was traveled by Andrew during the whole trip? Part C: What is the magnitude, in kilometers, of Andrew's displacement for the entire trip and what was the direction of his displacement for the entire trip?
