Answer:
u₂ = 3.7 m/s
Explanation:
Here, we use the law of conservation of momentum, as follows:
where,
m₁ = mass of the car = 1250 kg
m₂ = mass of the truck = 2020 kg
u₁ = initial speed of the car before collision = 17.4 m/s
u₂ = initial speed of the tuck before collision = ?
v₁ = final speed of the car after collision = 6.7 m/s
v₂ = final speed of the truck after collision = 10.3 m/s
Therefore,
<u>u₂ = 3.7 m/s</u>
Answer:
The water would rise because of displacement in the water
Explanation:
Answer:
A. 14.14 m/s²
B. 127.26 m/s
C. 572.67 m
Explanation:
From the question given above, the following data were obtained:
Mass (m) of jet = 4250 kg
Force (F) = 60100 N
A. Determination of the acceleration of the jet.
Mass (m) of jet = 4250 kg
Force (F) = 60100 N
Acceleration (a) =?
F = ma
60100 = 4250 × a
Divide both side by 4250
a = 60100 / 4250
a = 14.14 m/s²
B. Determination of the speed of the jet after 9 s.
Initial velocity (u) = 0 m/s
Acceleration (a) = 14.14 m/s²
Time (t) = 9 s
Final velocity (v) =?
v = u + at
v = 0 + (14.14 × 9)
v = 0 + 127.26
v = 127.26 m/s
C. Determination of the distance travelled during the time.
Initial velocity (u) = 0 m/s
Acceleration (a) = 14.14 m/s²
Time (t) = 9 s
Distance travelled (s) =?
s = ut + ½at²
s = (0 × 9) + (½ × 14.14 × 9²)
s = 0 + (7.07 × 81)
s = 0 + 572.67
s = 572.67 m.
