Question

a train is traveling at force 15000 N, how much work must it do to travel 10 km?

Answer 1

Answer:

W=1.5×10⁸J

Explanation:

first change the km to m then you get 10000m

• W=Fd
• W=15000*10000
• W=1.5×10⁸J

Answer 2

Answer:

150000000 Joule OR 1,5 *10^8 Joule

Explanation:

First transform the kilometers in meters:

10km = 10000 m (multiply by 1000)

Then to calculate the work using the the formula W= F * s where W is the work, F is the force and s is the distance traveled.

W= 15000*10000 = 1,5*10^8 J
