(05.08a)two similar triangles are shown on the following coordinate grid:
which set of transformations has been performed on triangle xyz to form triangle x″y″z″?

dilation by a scale factor of 4 followed by reflection over the x-axis
dilation by a scale factor of 2 followed by reflection over the y-axis
dilation by a scale factor of 4 followed by reflection over the y-axis
dilation by a scale factor of 2 followed by reflection over the x-axis

1) Kinetic energy of the truck 1 is 600,000 joules.

Kinetic energy of the truck 2 is 1,837,500 joules.

2 a)Potential energy of truck 1 is 646,800 Joules.

b) Energy lose by the truck 1 just got converted into heat and sound energy during the collision.

Step-by-step explanation:

Mass of the truck 1 and truck 2,m = 3000 kg

Velocity of the truck 1, = = 20 m./s

Velocity of the truck 2, = 35 m./s

1. Kinetic energy of the truck 1:

Kinetic energy of the truck 2:

2.a) Energy loose by the truck 1:

Initial height of the truck on the hill = 22 m

At that height potential energy will be maximum:

Potential energy of truck 1 at that height =

b) Energy lose by the truck 1 just got converted into heat and sound energy during the collision.
