The two identical trucks are traveling in opposite directions, and truck B is carrying a heavy load. (a) Will the magnitude of the force exerted on truck A by truck B be greater than, less than, or equal to the magnitude of the force exerted on truck B by truck A

The force exerted on truck A by truck B will definitely be greater than the magnitude of the force exerted on truck B by truck A

Explanation:

According to the concept of momentum

Momentum is the product of a body's mass and its velocity.

Yes both trucks are the same, but truck B is carrying a heavy load which gives it more momentum that A, actually momentum is a function of mass

Momentum M=mass(m) x velocity (v)

work: w = fd (given)

work done by chet   =50*1 = 50 j

work done by mika =40*2 = 80 j

work done by sara =30*1.5 = 45 j

work done by bill =60*0.5 = 30 j

students in order from the greatest amount of work done to the least is mika> chet> sara> bill

hence option (b) is correct.

i really dont know but i will try okay.

so i think u would just add all them up and get your answer..
