**Text Transcription for Educational Website:****Problem Statement:**The sports car shown in Figure 1 has been designed such that the 260-kg engine $E$ and 165-kg transmission $T$ have been placed over the front and rear wheels, respectively. Their mass centers are located at $G_E$ and $G_T$. The mass center of the remaining 512-kg body and frame is located at $G_b$.**Part A:**If power is supplied to the rear wheels only, determine the shortest time it takes for the car to reach a speed of 80 km/h, starting from rest. The front wheels are free rolling, and the coefficient of static friction between the powered wheels and the road is $\mu_s = 0.56$. Neglect the mass of the wheels and driver.Express your answer to three significant figures and include the appropriate units.**Input Box:**\[ t = \]- **Value:** [Input Field]- **Units:** [Input Field]**Submit Button:**- [Submit]- [Request Answer]**Additional Options:**- [Provide Feedback]**Figure Description:**The diagram consists of a yellow sports car with measurements and labels indicating the positions of the car's mass centers:- The distance from the front of the car to $G_E$ is 0.5 m.- The distance from the front wheels to $G_b$ is 1.25 m.- The distance from the front wheels to the rear wheels is 1.70 m.- The distance from $G_T$ to the rear is 0.40 m.**Next Button:**- [Next >]This transcription is intended for an educational website to help users understand the problem setup and input necessary calculations.

3. A 5-kg crate is released from rest at Point A of a 20-kg ramp which is inclined at 40 degrees as shown in the figure below. The lengths of the ramp is 2 m. The interface between the ramp and the ground can be assumed to be frictionless. Use Newton's 2nd Law and the definition of the center of mass to determine the horizontal distance that the ramp has moved when the crate reaches Point B. Neglect the size of the crate. Does your answer depend on the frictional force between the crate and the ramp? e S

A box with mass m is on a frictionless inclined ramp, as shown. The ramp has an angle of θ with respect to the horizontal. The ramp is firmly attached to the inside of a car. The car is traveling to the right, and is slowing down. The car has a constant acceleration with magnitude a. You observe that the box doesn’t slide up or down the ramp. What is the angle of the ramp? Write your answer in variables, using only m, g, and a. This problem should be solved using the “recipe” taught in class. Focus Draw a free body diagram Identify the direction of the acceleration Write Newton's 2nd law (F=ma) Solve for unknowns Suppose that the driver now presses harder on the brakes. Would the box slide up the ramp, or slide down the ramp? Or would it not slide at all? No calculation required, but very briefly (one or two sentences) justify your answer. Draw a simple diagram if it helps!
1) A loaded wheelbarrow is pulled to the left with an acceleration a = 2 m / s? by a force P. In this motion, the wheelbarrow does not rotate and the force of friction as well as the effect of the rotation of the wheel may be neglected. The combined mass of the wheelbarrow and its load is 250 kg with center of mass at G. For this instant, determine the horizontal and vertical components of the force P and the normal reaction at B. a P G beal 60 cm 50 cm 1 m 20 cm
In a conceptual design, the power to move a bus comes from the energy stored in an onboard rotating flywheel. The flywheel has a mass of 1500 kg, a radius of gyration of 500 mm, and is brought to a maximum speed of 4000 rpm. If the bus starts from rest and acquires a speed of 72 kph at the top of a hill 20 m above the starting position, find the reduced speed of the flywheel. Assume 10% of the energy of the flywheel is lost due to frictional effects. Neglect the energy of the bus contained in the rotation of the wheels. The bus with flywheel is 10,000 kg.

A spherical bowling ball with mass m = 4.6 kg and radius R = 0.105 m is thrown down the lane with an initial speed of v = 9.5 m/s. The coefficient of static friction between the ball and the ground is 0.35 and the coefficient for kinetic friction is μ = 0.3. Once the ball begins to roll without slipping it moves with a constant velocity down the lane. 1) What is the magnitude of the angular acceleration of the bowling ball as it slides down the lane? 2) What is magnitude of the linear acceleration of the bowling ball as it slides down the lane? 3) How long does it take the bowling ball to begin rolling without slipping? 4) Once it begins to roll without slipping, what is the force of friction on the ball?
1. Two blocks are connected by a pulley system shown in the figure below. Neglect friction between the block on the left and the ramp sloped at angle 0.

(a) Find the mass of the block on the right? (b) Find the velocity of the block on the left.

A slender bar with a length of 2 ft is pin-connected with a roller positioned on a smooth horizontal surface. The bar is at rest initially, and a horizontal force F is applied to the roller. If F = 13 lb and the weight of the bar is 10 lb, calculate the magnitude of the acceleration of the roller at that instant by neglecting the mass and the size d of the roller. Present your answer in ft/sec² using 3 significant figures. FOR COMARCA 2 ft F
