Answer:
1.8 m/s
Explanation:
m = mass of the automobile = 3690 kg
k = force constant of the spring = 8 x 10⁶ N/m
x = compression of the spring = 3.86 cm = 0.0386 m
v = speed of the car before impact
Using conservation of energy
Kinetic energy of automobile before impact = Spring potential energy of bumpers
(0.5) m v² = (0.5) k x²
(3690) v² = (8 x 10⁶) (0.0386)²
v = 1.8 m/s
Answer:
1.27 m/s.
Explanation:
The following data were obtained from the question:
Displacement (D) = 28 m
Time (t) = 22 secs
Velocity (v) =?
Velocity is simply defined as the rate of change of displacement of an object with time. It can be represented mathematically as:
Velocity (v) = Displacement (D) /Time (t)
v = D/t
With the above formula, we can obtain the swimmer's velocity as follow:
Displacement (D) = 28 m
Time (t) = 22 secs
Velocity (v) =?
v = D/t
v = 28/22
v = 1.27 m/s
Therefore, the swimmer's velocity is 1.27 m/s.
If i am reading this question right the answer should be the south pole
I am pretty sure it is A Becoming warm
Since it’s moving and causing friction which makes it warm
Hope this helps
