A300-w blender did 10,500j of work. how long was the blender running?

The blender was running for 35 seconds.

Explanation:

Given:

Power of the blender is,

Work done by the blender is,

We know that, power is defined as the rate at which work is done by the body.

Here, we are given the power and work done and we are asked to find time taken.

Let the time of running of the blender be 't' seconds.

So, the power of the blender is given as:

Rewriting the above in terms of 't', we have

Plug in the given values and solve for 't'. This gives,

Therefore, the blender was running for 35 seconds.

be subject to a force andchange its motion

we're given that v₀ = 0 and a = 5.4 m/s². therefore, since v = at + v₀ for constant acceleration the equation for velocity is

after 28s,

m/s

which i would round to 150 m/s as my final answer
