Amine car (mass mcar = 450 kg) rolls at a speed of vcar = 0.55 m/s on a horizontal track, as the drawing shows. an mcoal = 140 kg chunk of coal has a speed of vcoal = 0.73 m/s when it leaves the chute. determine the speed of the car-coal system after the coal has come to rest in the car. (assume the angle α = 26°.)

The speed of the car-coal system after the coal has come to rest in the car is 0.37 m/s.

Explanation:

Given that,

Mass of car = 450 kg

Velocity of car = 0.55 m/s

Mass of coal = 140 kg

Velocity of coal = 0.73 m/s

Suppose the angle is horizontal angle .

We need to calculate the speed of the car-coal system after the coal has come to rest in the car

Using conservation of momentum

Put the value into the formula

Hence, The speed of the car-coal system after the coal has come to rest in the car is 0.37 m/s.

i guess it’s a and b

i just did an experiment like this in my science class. also the answer is yes, it will get separated because they are two opposites meaning if they are opposite they can not attract.

hope this .!
