A subway car whose mass is 52,000. kg is traveling with a velocity of 3.4 m/s due north and collides with a second subway car whose mass is also 52,000. kg and is at rest. If the two cars stick together after the collision, what is the velocity of the two cars?

b.a device that inputs heat into a cool object

we're given that v₀ = 0 and a = 5.4 m/s². therefore, since v = at + v₀ for constant acceleration the equation for velocity is

after 28s,

m/s

which i would round to 150 m/s as my final answer

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
