    Conservation of energy of a truck problem

    I tried many ways to perfomr this problem, but i just can't figure out whether or not I am using the right values. "A 25 ton truck loses it brakes and reaches the bottom of a hill with a speed of 60 mph. Fortunately, there is a runaway truck ramp which is inclined at angle of 15 degrees to...

    Solving a Physics Question: Truck vs Car at the Lights

    Hello, I'm having some difficulty in a physics question. The question is: To save fuel, some truck drivers try to maintain a constant speed when possible. A truck traveling at 81.0 km/h approaches a car stopped at the red light. When the truck is 94.6 meters from the car the light turns...

    Solving the Physics Problem: Car and Truck Acceleration

    I'm not really good at physics so relevant any feedback would be helpful. Here's the question; At the instant a traffic light turns green, a car starts with a constant velocity of 6.0 ft/s. At the same instant a truck, traveling with a constant speed of 34 ft/s, overtakes and passes the car...

    Calculating Total Weight of a Truck with Uneven Loads

    A trucker needs to weigh a truck that is too long to fit on a platform scale. When the front wheels of the truck are run onto the scale, the scale reads W_1 . When the rear wheels are run onto the scale so that the front wheels are off, it reads W_2 . a) prove that the total wight of the...

    Driving a car on to the back of a moving truck

    Okay, and odd title, but let me continue. I recently read a 15+ page argument on another board about what would happen in the following scenario... You are traveling 62mph(~100kph). There is another vehicle (let's say, a car carrier truck as pictured below, with a ramp to the roadway :p )...

    Torque, Force, and a truck cover

    Hello... I am doing a little retrofitting with my Tonneau cover and my truck, but I need some help. I have cut my cover length-wise down the center, and need to rework the gas springs that hold the doors open. Here is the situation: Each door weighs 56 pounds, and is 32" wide. They are...

    Kinetic Energy: Calculating Fuel Use of a Truck

    Ok, I have tried to rationalize this problem, but I am stuck, I don't even know how to start! I know it has to do with kinetic energy though. When a truck goes from rest to 30 miles per hour, it uses one ounce of fuel. HOw many ounces of fuel does it use when it goes from 30 miles per hour to...

    Determine whether the truck will remain at rest

    hi can you help me with these two exercises please question 1 a 1490 kg car is moving with a steady speed of 88km/h at a constant height h above the ground on a slop track with an inclination angle to the horizontal. if there is no side force on the tyres determine(a)the radius of curvature...

    Solving Mechanics Problems: Truck Movement on Hills & Ramps

    These are two separate questions, each of them together, in a way. 1. A truck rolls down a 7.8 degree hill with a constant speed of 30.0 m/s. At the bottom of the hill it continues on a horizontal surface. How far will the truck go before it stops? For this I made a diagram with a...
