A car collides with a truck. The force exerted by the truck on the car is

A)	less than the force exerted by the car on the truck

B) greater than the force exerted by the car on the truck

C) the same as the force exerted by the car on the truck

D) not necessarily related to the force exerted by the car on the truck.

Expert Solution

The two vehicles experience a force of the same magnitude due to Newton's third law:

If object A exerts a force FAB on object B, then object B will exert a fore FBA on object A and

FBA=−FAB

However, what you're probably thinking about is that motion of the car is more drastically affected by the collision. This can be explained by Newton's second law. Let's say the truck has mass M and the car has mass m. If the magnitude of the force that both vehicles experience is F, then the magnitudes of their respective accelerations are

atruck=F/M, acar=F/m

and combining these we get

atruck/acar=m/M

So if the mass of the car is a lot less than the mass of the truck, then the acceleration of the truck is much smaller than the acceleration of the car, and if you were to watch the collision, the truck would pretty much seem like it's motion was unaffected, but the car's motion will change quite a bit.so option c is correct

A car of mass 2400 kg collides with a truck of mass 4500 kg, and just after the collision the car and truck slide along, stuck together, with no rotation. The car's velocity just before the collision was <35, 0, 0> m/s, and the truck's velocity just before the collision was <-10, 0, 21> m/s. What is the increase in internal energy of the car and truck (thermal energy and deformation)?

the force exerted by a spring is given by the equation where F is the force (in Newtons), xis the displacement of the spring from the equilibrium position (in centimeters), and k is a spring constant Create an Excel worksheet showing force as a function of displacement for two springs whose spring constants are 0.1 N/cm and 0.5 N/cm. Use displacements ranging from 0 to 20 cm (i.e. let x = 0, 1, 2 … 20 cm).

As shown below, a 840 kg car traveling east collides with a 1730 kg pickup truck that is traveling north. The two vehicles stick together as a result of the collision. After the collision, the wreckage is sliding at vf = 19 m/s in the direction θ = 25° east of north. Calculate the speed of each vehicle before the collision. The collision occurs during a heavy rainstorm so you can ignore friction forces between the vehicles and the wet...
