given that initial velocity is
deceleration is given as
now we have to find the distance covered in 16 s
so it will cover 137.6 m distance
part b)
in order to find the final speed
so its speed will be 6.2 m/s
Correct Answer: Option C
<em>Explanation
</em>
X = ut + 12at2
= (0 x 4) + (12 x 0.1 x 4 x 4)
= 0.8m
workdone = force x distance
= 40 x 0.8
= 32J
Answer:
1you need too add the 3 and then multiply the answer by 3 answer 39? im not sure
Answer:
The final velocity of the vehicles will be -75km per hour (leftwards).
Explanation:
Let us call , mass and velocity of the truck , mass and velocity of the car, and the final velocity of the vehicles.
The law of conservation of momentum states that
solving for we get:
putting in numerical values
(<em>the negative sign indicates that the vehicles are moving in the leftward direction)</em>
or -75.8 km per hour.<em> </em>
The basic building block of matter are Atoms. Atoms are also made up of Electrons, Protons, and Neutrons.
