An object of mass 5.00 kg is attached to a spring with a force constant of 300 N/m. It is oscillating on a horizontal frictionless surface with an amplitude of 2.00 m. A 8.00 kg object is dropped vertically on top of the 5.00 kg object as it passes through its equilibrium ...

**free fall**

A ball is thrown upward. While the ball is in the air, does its acceleration increase, decrease, or remains the same? Describe what happens to the velocity of the object from when it is thrown until when it returns.

**Physics/Science #3**

A ball is thrown vertically downward from the top of a 35.9-m tall building. The ball then passes the top of a window that is 10.7 m above the ground 2.00 s after being thrown. What is the speed of the ball as it passes the top of the window? The equation for the speed of the ...

**Physics**

An object m of mass m=1kg is attached to a string that passes through a hole in the center of a table. The object m moves in a circle of radius r=1.3m. An object M of mass M=2.1kg is tied to the other end of the string, and hangs vertically beneath the table. Assuming the ...

**physics**

A ball thrown vertically upward has an upward velocity of 5.68 m/s at a point 11.9 m above where it was thrown. How long does the ball take to reach that point?

**Physics**

A small circular object with mass m and radius r has a moment of inertia given by I = cmr^2. The object rolls without slipping along the track shown in the figure. The track ends with a ramp of height R = 3.0 m that launches the object vertically. The object starts from a ...

**pHYSICS**

A BALL IS THROWN STRIAGHT UPWARD AND RETURMS TO THE THROWER'S HAND AFTER 3 SECONDS IN THE AIR. A SECOND BALL IS THROWN AT AN ANGLE OF 30 DEGREES WITH THE HORIZONTAL. AT WHAT SPEED MUST THE 2ND BALL BE THROWN SO THAT IT REACHES THE SAME HIEGHT AS THE ONE THORWN VERTICALLY? I ...

**PHYSICS**

An object is thrown straight upwards from the ground at 28 m/s. Due to air resistance (a non-conservative force), the object loses 31.4 percent of its initial energy during its trip to reach maximum height. How much higher does the object travel if there was no air resistance...

**Physics**

An object is thrown upwards at an initial speed of 19.6 m/s from a height of 65m. Determine how long will take for the object to reach the ground (time of flight). what formula should i use?

**Physics**

A rock is thrown vertically upward with a speed of 11.0 from the roof of a building that is 70.0 above the ground. Assume free fall. In how many seconds after being thrown does the rock strike the ground? What is the speed of the rock just before it strikes the ground? The ...

**Algebra 2**

If an object is thrown vertically upward with an initial velocity of v, from an original position of s, the height h at any time t is given by: h=-16t^2+vt+s (where h and s are in ft, t is in seconds and v is in ft/sec) If a rock is dropped from the top of a 200 ft building, ...
