Answer:
4.78 m/s^2
Explanation:
A)From he FBD
we can write
Tcosθ= mg
Tsinθ= ma
dividing we get tanθ= a/g
a= g tanθ
a= 9.81 tan26°= 4.78 m/s^2
This is an example of Negative Acceleration because its speed is decreased.
Answer:
The shape and volume of the liquid metal will change into the shape and volume of the block-shaped mold.
Explanation:
Any type of liquid takes up the space in it's container. It is a physical change and nothing else will change besides the shape and volume.
Explanation:
7) Given:
v₀ = 2.0 m/s
v = 0 m/s
t = 3.00 s
Find: Δx
Acceleration isn't included in the problem, so use a kinematic equation that doesn't involve a.
Δx = ½ (v + v₀) t
Δx = ½ (0 m/s + 2.0 m/s) (3.00 s)
Δx = 3.0 m
8) Given:
v₀ = 0 m/s
v = 5 m/s
t = 4 s
Find: a
Displacement isn't included in the problem, so use a kinematic equation that doesn't involve Δx.
v = at + v₀
5 m/s = a (4 s) + 0 m/s
a = 1.25 m/s²
9) Given:
v_avg = Δx / t
0.5 m/s = 8 m / t
t = 16 s
