How much force is required to move a sled 5 meters if a person uses 60 j of work? 300N 12N 65N 30N

1 answer:

4 0

The answer is b 12N because
We know that
W = F × d × c o s(θ)
assuming theta=0 we then solve and have
F=W/d
substitute known values to get:
F=60J/5m=12N

The record for the highest speed achieved in alaboratory for a

Ira Lisetskai [31]

Answer:

0.000234 seconds

Explanation:

Since the row is 0.15m, its radius of rotation must be 0.15 / 2 = 0.075 m

We can start by calculating the angular speed of the rod:

$\omega = \frac{v}{r} = \frac{2010}{0.075} = 26800 rad/s$
