friction between the block and the plane is 0.4 2. Due to friction the body will decelerate Let the deceleration be ‘a’ R – mg = 0 R = mg ...(1) ma – R = 0 ma = R = mg (from (1)) a = g = 0.1 × 10 = 1m/s2. Initial velocity u = 10 m/s Final velocity v = 0 m/s a = –1m/s2 (deceleration) S = 2a v2 u2 = 2( 1) 0 102 = 2 100 = 50m It will travel 50m before coming to rest. 3. Body is kept on the horizontal table. If no force is applied‚ no frictional force will be there

The Effects of Force and Mass on an Object’s Acceleration Abstract: In this lab there were two principals investigated. The first was the relationship between applied force and acceleration. The second was the relationship between mass and acceleration. To study these two relationships‚ my partners and I used a dynamic cart with added mass on it. This cart was then attached to a pulley system on a “frictionless track” where it was pulled by a string bearing mass over the edge

argument rests on a fact‚ a fundamental truth‚ a right‚ or a value. Gilb’s story “Al in Phoenix‚" tells of a guy‚ who is the narrator‚ whose car breaks down in Phoenix‚ Arizona. The narrator dials Triple-A hoping they could help him out with the car. A tow truck arrives and takes his car to a mechanic that was well-known in the city of Phoenix‚ Arizona. The mechanic named Al was long-familiar for fixing any car’s troubles and not charging so much for a single tire placement. The narrator was worried that

time it takes. Theory: Hence the gravitational acceleration “g” can be calculated by this equation: T=2πLg T=2πLg (T the period in seconds‚ l the length in meter and g the gravitational acceleration in m/s2) Method: As stated earlier in the introduction‚ it was decided to measure the time for 10 complete swings‚ in order to reduce the random errors. These measurements would be repeated two more times‚ and in total five successive lengths were used

11 Service Department and Joint Cost Allocation Solutions to Review Questions 1. Companies allocate costs to estimate or assess the costs of their activities (products‚ processes‚ etc.). It is an estimate and subject to the problem that cost allocation contains an arbitrary element. Not allocating costs‚ however‚ is also an estimate—an estimate of zero. This may be appropriate for some decisions‚ but not for others. Some of the disadvantages (costs) include: (1) Additional

SECTION 2 SECTION REVIEW 1. Marissa’s car accelerates uniformly at a rate of +2.60 m/s2. How long does it take for Marissa’s car to accelerate from a speed of 24.6 m/s to a speed of 26.8 m/s? 2. A bowling ball with a negative initial velocity slows down as it rolls down the lane toward the pins. Is the bowling ball’s acceleration positive or negative as it rolls toward the pins? 3.

Uniform Circular Motion PES 115 Report Objective The purpose of this experiment is to determine the relationships between radiuses‚ mass‚ velocity and centripetal force of a spinning body. We used logger pro to accurately measure the orbital period of the spinning mass and used these measurements to determine the interrelated interactions of the specified properties and viewed the results graphically.
