Do a truck and a car have equal kinetic energy? Both the truck and the car had same kinetic energy and hence same amount of work is needed to be done. As retarding force applied is same for both, therefore, both...
What happens to the amount of energy if speed is doubled in a vehicle collision? This means that when the velocity of an object doubles, its kinetic energy quadruples. A car traveling at 60 mph has four times the kinetic energy...
What is the kinetic energy of a car of mass 500kg moving with a velocity of 36km h? Velocity of car, v = 36 km/hr = 36 × (5/18) = 10 m/s. Mass of car , m = 500 kg. Kinetic...
What is a truck of mass 1800 kg moving with? A truck of mass 1800 kg is moving with a speed 54 km/h. When brakes are applied, it stops with uniform negative acceleration at a distance of 200 m. The force...
What will be the momentum of a car having mass of 1000 kg is moving with a velocity of 0.5 m s? We know that Momentum p = Mass m × Velocity v Therefore p = 1000 kg × 0.5 m/s...
Why does a car need forward force? The engine provides the force to turn the tires which, in turn, pushes backwards against the road surface. By Newton’s Third Law, the reaction of the surface to the turning wheel is to provide...
What is the formula for initial velocity? Let us take a quick look at those formulas. The first formula to find initial velocity is u = v – at. Is the velocity of a car is increased by 20% then the...
Does the air in a car move with the car? The basic mass of air would be fairly still. But real cars have ventilation in them that moves the air, even under a steady cruise. In what direction will a helium...
Is the velocity of a car is increased by 20% then the minimum distance in which it can be stopped increases by? If the velocity of car is increased by 20% then the minimum distance in which it can be stopped...
What is velocity of the two cars after the collision? Once the momentum of the individual cars are known, the after-collision velocity is determined by simply dividing momentum by mass (v=p/m). What is the speed V of a car moving on...
