Sam’s job at the amusᴇмᴇɴt park is to slow down and bring to a stop the boats in the log ride.
If a boat and its riders have a mass of 1100 kg and the boat drifts in at 2.2 m/s how much work does Sam do to stop it?
you use 1/2 m v^2
1/2 * 1100 * 4.84= 2662J
And your answer will need to be negative … -2662J
force=mass x acceleration
1100 x 2.2=2420Newtons
I’m pretty sure it would be 500JSource(s): My brain and gr.8 science textbook 😀
