Assume "forwards" is positive and "backwards" is negative. Which of the following statements about the motion of the cart is true? A. The cart is moving forwards and speeds up until 3s and then the cart slows down B. The cart moves forwards with a fixed speed until 3s and then moves backwards with a fixed speed C.

A student stands at the edge of a cliff and throws a stone horizontally over the edge with a speed of v0 = 22.0 m/s. The cliff is h = 37.0 m above a flat, horizontal beach as shown in the figure.(d) Write the equations for the position of the stone with time, using the coordinates in the figure. (Use the following as necessary: t. Let the variable t be measured in seconds. Do not state units in your answer.) x = y = (e) How long after being released does the stone strike the beach below the cliff? s(f) With what speed and angle of impact does the stone land? vf = m/s ? = ° below the horizontal
A child, who is L = 41 m from the bank of a river, is being carried helplessly downstream by the river's swift current of 1.0 m/s. As the child passes a lifeguard on the river's bank, the lifeguard starts swimming in a straight line until she reaches the child at a point downstream. a.) If the lifeguard can swim at a speed of 2.0 m/s relative to the water, how long does it take her to reach the child? Express your answer to two significant figures and include the appropriate units. b.)How far downstream does the lifeguard intercept the child? Express your answer to two significant figures and include the appropriate units.
A Turtle is moving with a constant acceleration along a straight path. He starts his stopwatch as he passes afence post and notes that it takes him 10.0 s to reach a pine tree 10.0 m farther along the path. As he passes the pinetree, his velocity is 1.2 m/s. How far from the fence post was he when he started? Use diagrams as part of your solutionand verify that your answer is correct.

Hi I am in physics 1 and I need help with this problem. It saids a boy runs in an open field. He runs 233m due north in 77 seconds, turns 90 degrees to his left and runs 178m in 93 seconds. Sketch a map of his motion and find the following quantities of his motion during this period from starting time to final time a) Map of his motion b) The total distance he runs (233m + 178m= 411m) c) The displacement from starting position to final position. What I have thus far is I got c=sqrt (233)^2+(178)^2=293m. Would I subtract this number from the total distance? Please includes detailed steps of how to solve this
A river has a steady speed of 0.650 m/s. A student swims upstream a distance of 1.00 km and swims back to the starting point. If the student can swim at a speed of 1.50 m/s in still water, how long does the trip take (swimming up and down in the current)? Your response differs from the correct answer by more than 10%. Double check your calculations. sIf the water were still, by how much would the trip be longer or shorter? (Give a negative answer for a shorter trip.)
Gaby and her cousin, Fiona, live 45 km apart. Every day, they drive by one another to get to work. Gaby leaves home at 7:00 a.m. and drives at the road speed of 60 km/h. Fiona, however, always leaves home 20 min later and therefore speeds by 10 km/h. Approximately what time will Gaby meet Fiona on the road?
