A 150 ice puch collides need on a smaller 100g ice puch, initially stationary, on a smooth, directionless surface. The initial speed of the 15pg puch is 3m/s .After the collision the 100g ice puch moves with a speed of 1.2m/s in the same direction. What is the final velocity of the 150 ice puch?

explanation:

as the height from which the ruler was dropped increased, the speed of the ruler at ryan's hand increased.

a) electrical > light, sound, and thermal< < < <

) the mechanical energy of the firefighter moving.< < < < a) electrical > light, sound, and thermal< < < <

c) both a and b.

it is a negative acceleration

find the surface area of the sphere to the nearest square unit. use a calculator.

a. 254 in.2

b. 64 in.2

c. 127 in.2

d. 1,018 in.2
