A kid pulls on a rope with 20 newtons of force. The block and tackle system pulls up a 160 newton box. What is the mechanical ad
Minchanka [31]
Answer:
The mechanical advantage of the system is 8

Explanation:
the mechanical advantage measures how much the system multiplies the input force to get the output.

In the given:
The input force (effort) is 20 Newton
The output force (load) is 160 Newton

This means that the mechanical advantage is:
mechanical advantage = load / effort = 160 / 20 = 8

Note that the mechanical advantage is unit-less (has no unit) since it is a ratio between two forces.

Hope this helps :)

A girl rides her bike at 2.52 m/s on the way to her friends how which is 628 m away.
Harrizon [31]

Answer: 249 seconds

Explanation:

Speed of bike = 2.52 m/s

Distance = 628 m

Time taken = ? ( let the unknown value be Z)

Recall that speed is the distance covered per unit time.

Hence, speed = Distance / Time taken

Time taken = Distance / speed

Z = 628m / 2.52 m/s

Z = 249.2 seconds (Round to nearest tenth i.e 249 seconds)

Thus, it takes 249 seconds for the girl to get to her friends house
