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
Answer:
As we know that friction force always oppose the motion of body.In other words we can say that friction act opposite to the direction of motion of the body.It tries to stop the body is body is in motion.The value of friction force varies and reaches up to a maximum value.If the body is in rest condition then friction force will be static friction and the body is in moving position then the friction force will be kinetic friction.
Here given that we apply a force in the right direction then friction will act in the left direction.
Wood, marble, clay, terracotta and even concrete all come in colors and can be classified as natural materials.
Answer:
Your friend is 2.143 blocks from the restaurant.
You are 2.857 blocks from the restaurant.
Explanation:
Let t be the time both you and your friend take to walk to the restaurant.
The distance (m) from your building to the restaurant is your walking time t times your speed v1
Similarly the distance (m) from your friend building to the restaurant:
Let b be the length (in m) of a block, the total distance of 5 blocks is 5b
So your friend are 2.143b meters from the restaurant, since each block is b meters long, 2.143b meters would equals to 2.143b/b = 2.143 blocks. And you are 5 - 2.143 = 2.857 blocks from the restaurant.
Responder:
35,2 ohm.
Explicación:
Dado:
La resistencia específica del conductor es,
La longitud del conductor es,
El área de la sección transversal del conductor es,
Sabemos que la resistencia de un conductor es directamente proporcional a su longitud e inversamente proporcional al área de la sección transversal.
Por lo tanto, la resistencia se puede expresar como:
Ahora, conecte los valores dados y resuelva para 'R'. Esto da,
Por lo tanto, la resistencia del conductor es de 35,2 ohm.
