A car starts from rest and travels for 5.0s with a uniform acceleration of -1.5m/s2. What is the final velocity of the car? How far does the car travel in this time interval? vf = vi + a(Dt) or vf = (0 m/s) + (-1.5 m/s2)(5.0 s) = -7.5 m/s Dx = vi(Dt) + 1/2a(Dt)2= Dx = (0)(5.0 s) + 1/2(-1.5 m/s2)(5.0 s)2 = -18.75

Projectile Motion You have probably watched a ball roll off a table and strike the floor. What determines where it will land? Could you predict where it will land? In this experiment‚ you will roll a ball down a ramp and determine the ball’s velocity with a pair of Photogates. You will use this information and your knowledge of physics to predict where the ball will land when it hits the floor.

CHAPTER 1: Introduction‚ Measurement‚ Estimating Answers to Questions 1. (a) Fundamental standards should be accessible‚ invariable‚ indestructible‚ and reproducible. A particular person’s foot would not be very accessible‚ since the person could not be at more than one place at a time. The standard would be somewhat invariable if the person were an adult‚ but even then‚ due to swelling or injury‚ the length of the standard foot could change. The standard would not be indestructible – the foot would

the specific energy E in an open channel with respect to channel bottom is defined by equation 1. E = y + v22g Eq. 1 Where E is the specific Energy in distance (L)‚ v is the velocity in (L/T)‚ y is the depth of flow in (L)‚ and g is the acceleration of gravity in (L/T2). Based on this equation‚ the energy before the weir is equal to the energy over the weir plus the height of the weir as shown in equation 2. E1 = E2 + Δz Eq. 2 From the known discharge‚ the velocity of the flow can be
