Answer:
4.4 km
Explanation:
t = Time taken
u = Initial velocity = 24 m/s (Assumed)
v = Final velocity
s = Displacement
a = Acceleration = -0.065 m/s² (Assumed)
Distance = Speed × Time
The train travels for 9600 m.
The Distance the train traveled when it slowed down is 4.4 km
Answer:
S & O
Explanation:
Electrons can be shared when both atoms are non-metal.
(called Covalent Compound)
The initial kinetic energy of the boat and its rider is
After Sam stops it, the final kinetic energy of the boat+rider is
because its final velocity is zero.
For the law of conservation of energy, the work done by Sam is the variation of kinetic energy of the system:
where the negative sign is due to the fact that the force Sam is applying goes against the direction of motion of the boat.
C is the answer
D is impossible
A and B are false
Hope this helps!
