A toy railway cart of mass 500 g is sitting on a rail, so that it can roll freely. A metal ball of mass 200 g is suspended on a string, in such a way that it is just touches the cart when the string is hanging vertically.

The metal ball is then pulled to the side so that it is raised by 10 cm when the string is taut.

a. If the ball is released from rest, what is its velocity (in m s − 1) as it strikes the cart? Give your answer to 1 decimal place.

b. If the metal ball comes to rest as it hits the cart, what is the velocity (in m s − 1) of the cart after the collision? Give your answer to 2 decimal places.

c. If the impact took 0.12 seconds, what was the magnitude of the average force between the ball and the cart? Give your answer to 1 decimal place.

A cart of mass m1(pictured) is free to move nearly frictionless up a ramp at angle θ. A small mass m2 hangs from a string that runs over a pulley and connects to m1. We will determine the acceleration of the cart m1 over a known distance x,then plot the acceleration of m1 as a function of the hanging mass m2. a) The hanging mass will create a constant pulling force to accelerate the cart up the ramp. Using Newton’s...

1) A thin rod of length 0.64 m and mass 150 g is suspended freely from one end. It is pulled to one side and then allowed to swing like a pendulum, passing through its lowest position with angular speed 1.46 rad/s. Neglecting friction and air resistance, find (a) the rod's kinetic energy at its lowest position and (b) how far above that position the center of mass rises. 2) A wheel, starting from rest, rotates with a constant angular...

A mountain climber of mass m=75.0 kg slips during a climb and begins to fall freely. She forgot her rope and had to use an ideal spring. The spring is hanging vertically with an unstretched equilibrium position at the origin, x=0. On her descent, she grabs the end of the spring which has a spring constant of k= 981 N/m. Ignore friction, air resistance, and any other dissipative effects. a) The climbers velocity when she grabbed the spring was 20.0...

Please answer all, Thank you. 1. A firework is designed so that when it is fired directly upwards, it explodes and splits into three equal-massed parts at its peak. Someone launches the firework directly upwards and measures the locations of two of the pieces of the firework. They find that one piece landed 2 meters to the left and another piece landed two meters in front of them. Where did the third piece of land? 2. A Newton's cradle is...

Finding the Spring Constant We can describe an oscillating mass in terms of its position, velocity, and acceleration as a function of time. We can also describe the system from an energy perspective. In this experiment, you will measure the position and velocity as a function of time for an oscillating mass and spring system, and from those data, plot the kinetic and potential energies of the system. Energy is present in three forms for the mass and spring system....
