You are on a planet with an unknown acceleration due to gravity. You drop an objectfrom rest and a height 2.8 metres, and measure the final speed 7.4 m/s as the objecthits the ground. Using the Principle of Conservation of Energy, calculate themagnitude of the acceleration due to gravity. Use one digit of precision in youranswer.

How much work (in J) is done for an object moving from x=1m to x=5m?
A pendulum consists of a small object hanging from the ceiling at the end of a string of negligible mass. The string has a length of 0.79 m. With the string hanging vertically, the object is given an initial velocity of 2.8 m/s parallel to the ground and swings upward in a circular arc. Eventually, the object comes to a momentary halt at a point where the string makes an angle with its initial vertical orientation and then swings back downward. Find the angle 0. Number i Units
An object of mass m = 2.9 kg is free to move on a horizontal surface without any friction. It is initially at rest and starts moving under a net force of F = (3N)i + (4N)j. What is the object's speed in m/s after moving 1 meter?
When a m = 12 kg mass is on a frictionless incline of 30 degrees and takes 270 N to compress a spring 2.0 cm: The block briefly stops when the spring is compressed to 5.5 cm a) How far did it travel. I found the answer is 35 cm b) What is the speed of the 12 kg block as it touches the spring? How do I do part b? I got the spring constant k = 13500 and used 1/2 kx^2 to find how many joules it has at compressing the spring to 5.5 cm. When I set that equal to 1/2 mv^2 I did not get the right answer. How would I go about finding b?
Suppose you have a spring (of constant k = 250) and you compress it 10 cm. next to the spring you place a frictionless cart of mass 250 g. The spring is released and the cart is pushed along a horizontal track. What speed (in m/s) does the cart obtain?
A toy cannon uses a spring to project a 5.40-g soft rubber ball. The spring is originally compressed by 5.09 cm and has a force constant of 7.97 N/m. When the cannon is fired, the ball moves 16.0 cm through the horizontal barrel of the cannon, and the barrel exerts a constant friction force of 0.032 3 N on the ball. (a) With what speed does the projectile leave the barrel of the cannon? m/s (b) At what point does the ball have maximum speed? cm (from its original position) (c) What is this maximum speed? m/s
A spring gun (spring constant k=100 N/m) is used to shoot a 10 g ball vertically up. Spring is compressed by 10 cm. a) What is the speed of the ball when it leaves the gun? 1. b) What is the maximum height of the ball above the release point?
A proton (mass m = 1.67 × 10-27 kg) is being accelerated along a straight line at 9.80 × 101¹1 m/s² in a machine. If the proton has an initial speed of 5.40 × 104 m/s and travels 3.80 cm, what then is (a) its speed and (b) the increase in its kinetic energy?
In order to stop a 15.0 kilogram block from sliding down a frictionless 40.0° incline, a powerful spring with k = 2.90 104 N/m is used. Blocks can travel up to 3.00 meters after they are released from their resting place against springs. How much of the spring's original tension will remain after the block comes to a halt?
An object is attached to a light string and is forced to move in uniform circular motion on a frictionless table.

A bowling ball is attached to a 2.91-meter long cable and hung from the ceiling. The cable is kept taut and the ball is raised to an initial height of 1.73 meters above the classroom floor. It is released from rest and allowed to swing as a pendulum. Determine its speed (in m/s) when it is at a height of 1.17 meters above the floor.
