Ablock is projected up a frictionless inclined plane with initial speed v0 = 6.48 m/s. the angle of incline is θ = 27.3. (a) how far up the plane does it go? (b) how long does it take to get there? (c) what is its speed when it gets back to the bottom?

distance = 4.67 m

time = 1.44s

speed = 6.48 m/s

Step-by-step explanation:

initial speed v₀ = 6.48 m/s

θ = 27.3⁰

a) distance traveled by the block

b) time taken to travel

c) speed at the bottom

h = L sinθ

h = 4.67× sin 27.3°

h = 2.14 m

by law of conservation of energy

speed equal to 6.48 m/s

step-by-step explanation:

in the attachment.   i didn't see your choices.   the word which means there is choices.

step-by-step explanation:

(x,y)

x tells you how much left or right you go from the origin

y tells you how much down or up you go from the origin

so for example (-3,2), you go left 3 and up twice. i denoted which of the ordered pairs is which in my graph.
