Practice Projectiles (Source for the first five problems WWW.MIAMI-BEST-MATH-TUTOR.COM‚ 1. 1. A physics book slides off a horizontal table top with a speed of 1.10 m/s. It strikes the floor in 0.350 s. Ignore air resistance. Find the height of the table top above the floor; the horizontal distance from the edge of the table to the point where the book strikes the floor; the horizontal and vertical components of the book’s velocity‚ and the magnitude and direction of its velocity‚ just before

The blue vector is accelerating toward the center. The green vector is perpendicular due to being tangent along the path of the circle. 4) Now move the ball at a slow constant speed across the screen. What do you notice now about the vectors? Explain why this happens. The vectors are not noticeable. The speed remains constant therefore there would not be acceleration. Velocity

AP Physics HW #1 Multiple Choice 1. A car travels 30 miles at an average speed of 60 miles per hour and then 30 miles at an average speed of 30 miles per hour. The average speed the car over the 60 miles is (A) 35 m.p.h. (B) 40 m.p.h. (C) 45 m.p.h. (D) 10 m.p.h. (E) 53 m.p.h. Answer: B. Method: Vavg = Δx/Δt The average speed is the total distance traveled‚ divided by the total time. They give us all distances traveled is‚ so we just need to find the time. We find the time‚ by applying

seconds. How many more seconds will he take to pass the remaining 4 flags ? 2. A person has to cover the fixed distance through his horses. There are five horses in the cart. They ran at the full potential for the 24 hours continuously at constant speed and then two of the horses ran away to some other direction. So he reached the destination 48 hours behind the schedule. If the five horses would have run 50 miles more‚ then the person would have been only 24 hours late. Find the distance of the destination

SAMPLE PROBLEMS: 111-SET #1 VECTOR ADDITION‚ SUBTRACTION 01-1 1). A man is able to row a boat at 3 mph in still water. If he rows his boat pointed straight across a river with a current of 4 mph‚ what is his net velocity? If the river is 0.5 miles wide‚ at what point will he land on the other side? Solution: The first step in problem solving is to identify the problem type. In this problem we are asked for a ‘net velocity.’ Since velocities behave as vectors‚ then we have a vector addition

Three years ago‚ the eagle was 7 times as old as the falcon. Find the present age of each bird. Solution x = falcon’s age now 4x = eagle’s age now {the eagle is 4 times as old as falcon} x - 3 = falcon’s age 3 years ago 4x - 3 = eagle’s age 3 years ago 4x – 3 = 7(x – 3) {three years ago‚ eagle
