Explanation:
s = ut + 1/2 a t^2
200 = 0 * 6 + 1/2 * a * (6)^2
200 = 1/2 * a * 36
200 = 18 a
a = 200/18
a= 11.1m/sec^2
v = u + at
v = 0 + 11.1 * 6
v = 66.6m/s
hope it helps you
Answer:
35 N to the right.
Explanation:
450 is going to the right so you subtract what is going against it. Which gives you 35. And because 450 is bigger than 415, it'll be going to the right.
Answer:
Mass and Acceleration
Explanation:
The typical Force equation is:
F = ma
where m = mass, and a=acceleration.
Answer:
Explanation:
mass of the alloy = 35.2 g
temperature t of the alloy = 93° C
heat loss by alloy = mc ( t₁ - t₂) where t₁ = 93 and t₂ = 31.1° C
heat loss by alloy = 2178.88 c where c is the specific heat capacity of the alloy
heat gained by water = m cw ( t₂ - t₁ ) where t₁ of water = 22° C and t₂ of water = 31.1° C
heat gained by water = 8338.294
heat gained = heat loss
2171.84 c = 8338.294
c specific heat capacity of the alloy = 8338.294 / 2178.88 = 3.83 J/g.K
