Two 0.5 kg carts, one red and one green ,sits about half a meter apart on a low friction track. You push on the red with a constant force of 4N for 0.17m and then remove your hand. The cart moves 0.33 m on the track and then strikes the green cart. What is the work done by you on the two cart system?

Work done  on the two cart system is 2 N-m

Explanation:

Work done is equal to the product of force and displacement

Work done =4N * (0.17 +0.33)

work done = 4N * 0.5

Work done = 2 N -m

Work done  on the two cart system is 2 N-m

the expression 15n + 2(3p) represents the amount isaiah spent buying gasoline and snacks, where n represents the price of each gallon of gasoline and p represents the cost of each snack that he bought. which statement is true about the amount isaiah spent?

see the picture for the vector

the magnitude of the vector by pythagorean theorem

r = √( (-10)^2 + (3)^2 ) = √109

magnitude = √109 units

the direction angle between vector and x-axis is

tan^(-1)(3/10) = 16.699

so the direction is approximately 16.7 degrees north of west
