Aboat cruises 60 meters west in 10 seconds. what is its instantaneous velocity? a. 6 m/s b. 6 m/s west c. 600 m-s west d. there is not enough information given to figure out the answer.

Write the equation for momentum, first using symbols for the variables, then using words for the variables.

Cathy is pedaling down a steep hill on her bicycle and wants to be able to coast up the next hill, which is 25 meters high, without pedaling. cathy and her bicycle have a mass of 75 kg. assuming her bicycle is 100% efficient, what would her speed have to be?

Assume you measured the mass of the cart to be (500 ± 1) g and the mass of the additional mass you put on the cart to be (500 ± 1) g as well. since the scale you are using in the lab cannot measure objects heavier than 600g you will have to sum up individual pieces and propagate the error. so what would be the mass and the standard error of the cart and the mass
