The Average acceleration is 3.25m/s².
Acceleration is the change in velocity of the body with respect to time.
Where,
a= acceleration
u= initial speed
v= final speed
t= time
Initially, u = 2m/s
v = 16m/s
t = 3.5s
a = v-u/t
a = 16-2/3.5
a = 4m/s²
Then, u = 26m/s
v = 18m/s
t = 4s
a = v-u/t
a = 26-18/4
a =2 m/s²
Now, u = 0m/s
v = 20m/s
t = 2s
a = v-u/t
a = 20/2
a = 10m/s²
Finally, u = 20m/s
v = 10m/s
t = 2s
a = v-u/t
a = 10-20/2
a = -5m/s²
The average acceleration is the acceleration during the entire journey = 4+2+10-5/4
Average acceleration = 13/4m/s²
Average acceleration = 3.25m/s²
The Average acceleration is 3.25m/s²

Answer:
X = 15.88 m
Explanation:
Given:
Initial Velocity V₀ = 13.4 m/s
θ = 30.1 °
g = 9.8 m/s²
To Find horizontal distance let "X" we have to time t first.
so from motion 2nd equation at Height h = 0
h = V₀y t + 1/2 (-g) t ² (ay = -g)
0 = 13.4 sin 30.1° t - 0.5 x 9.81 x t² (V₀y = V₀ Sin θ)
⇒ t = 1.37 s
Now For Horizontal distance X, ax =0m/s²
X = V₀x t + 1/2 (ax) t ²
X = 13.4 m × cos 30.1° x 1.37 s + 0
X = 15.88 m

Answer:
24.24L
Explanation:
According to Boyle's law which states that "the volume of a given mass of gas at constant temperature is inversely proportional to its pressure". Mathematically, P = k/V where;
P is the pressure
V is the volume
k is the proportionality constant
PV = k
P1V1 = P2V2
P1 and P2 are initial and final pressure respectively
V1 and V2 are the initial and final volume respectively
Given P1 = 101kPa V1 = 6.0L, P2 = 25kPa V2 = ?
From the formula;
V2 = P1V1/P2
V2 = 101×6/25
V2 = 24.24L
The final volume for the gas is 24.24L
