A cart is released from rest from the top of an inclined ramp. Ignoring friction, which of the following is the best representation of the x-position vs. time graph for the cart as it rolls down the ramp. Assume x = O is at the top of the ramp, t = 0 occurs at the moment the cart is released, and the +x axis points directly down the ramp.

A common graphical representation of motion along a straight line is the v vs. t graph, that is, the graph of (instantaneous) velocity as a function of time. In this graph, time t is plotted on the horizontal axis and velocity v on the vertical axis. Note that by definition, velocity and acceleration are vector quantities. In straight-line motion, however, these vectors have only a single nonzero component in the direction of motion. Thus, in this problem, we will call the velocity and a the acceleration, even though they are really the components of the velocity and acceleration vectors in the direction of motion, respectively.

A person throws a ball with speed 102 m/s at a 45° angle. How many seconds faster would the ball arrive if the person threw the ball at the same speed and the same distance but made the trip in two identical bumps. Assume that there is no loss of speed at the bounce. Hint: Use R = v2/g * sin(2θ) and t=2*vy(sinθ)/g.
I am currently learning about kinematics in my physics class. For one of the questions, it asks me to solve a question that asks me to find the magnitude of acceleration. I have found answers ranging between 3 and 4, but everytime I put my answer into Webassign it is wrong. I was wondering how I would find the magnitude of acceleration given the time and distance. Thank you
Standing on the roof of a 95-m tall building, a girl holds her hand past the edge and throws a ball straight up at 8 m/s. The ball rises, then falls and strikes the ground. Considering "up" to be the positive direction, find the ball's velocity v when it is 40 m above the ground. Remember to include a "-" sign if the velocity is negative. V = m/s
A ball is thrown eastward into the air from the origin (in the direction of the positive x-axis). The initial velocity is 40 i +64 k, with speed measured in feet per second. The spin of the ball results in a southward acceleration of 4 ft/s2, so the acceleration vector is a = -4 j - 32 k. Where does the ball land? (Round your answers to one decimal place.) X ft from the origin at an angle of 5.7 X from the eastern direction toward the south. 80.4 With what speed does the ball hit the ground? (Round your answer to one decimal place.) 61.3 X ft/s Submit Answer
A student stands at the edge of a cliff and throws a stone over the edge at an angle 0 above the horizontal. Ignoring the effects of air resistance, which of the following statements must be true? (There may be more than one correct answer). A plot of the horizontal position x vs. time t will have a constant and positive slope The horizontal range of the stone equals vo2sin(20)/g There is no point in the stone's motion in which the stone's speed matches its initial speed. A plot of the vertical velocity component vy vs. time t will have a constant and negative slope When the stone reaches its maximum height, its velocity will be zero
A boxer's fist and glove have a mass of m = 1.04 kg. The boxer's fist can obtain a speed of v = 9.25 m/s in a time of t = 0.21 s. Write a symbolic expression for the magnitude of the average acceleration, aave, of the boxer's fist, in terms of the variables provided. Find the magnitude of the average acceleration, aave, in meters per square second. Write an expression for the magnitude of the average net force, Fb, that the boxer must apply to his fist to achieve the given velocity. (Write the expression in terms of m, v and t.) What is the numerical value of Fb, in newtons?
An object moves in the x-y plane with a constant acceleration of 2i +3j meters per second squared. The object starts at the origin with some initial velocity. After four seconds (4 seconds) the velocity of the object is 2i + 8j meters per second. Determine the object’s initial velocity. Leave answer in i-j notation. Determine the position of the object at time, t = 4 seconds. Leave answer in i-j notation. Thank you for your help.
