A cart on a linear track has a uniform acceleration of 0.172m/s2. What is the velocity of the cart 4.00 s after it is released from rest?

a stone is thrown straight upwards the top of building with an initial velocity of 20m/s. determine its maximum height

In the medium wave radio band, waves sent out by the transmitter, T, may reach the receiver, R, by two routes: the ground wave travels direct, while the sky wave is returned to earth by the layers of ionized gas collectively called the ionosphere. 1) The height h of the ionosphere may vary over a...

A uniform beam is 5.0 m long and has a mass of 65 kg. In the figure below, the beam is supported in a horizontal position by a hinge and a cable, with angle = 55 . In unitvector notation, what is the force on the beam from the hinge

In excel problem 1, is the assumption that the cost of each stock is $1?

A merrygoround is 11m in diameter. The outermost horses are set at a diameter of 10m. If the merrygoround spins at 2 RPM what is the tangential speed of the outermost horses?

A motor is capable of 1000 watt of power how large a mass can it lift at 75 m in 20 seconds

Suppose a net external force of 50.0 N is exerted and the astronaut s acceleration is measured to be 0.893 m/s2. (a) Calculate her mass.

Tips for Asking Questions
 Provide any and all relevant background materials. Attach any necessary files to ensure your Tutor has all the required information to answer your question as completely as possible.
 Set a compelling price. While our Tutors are eager to answer your questions, offering a compelling price speeds up the process by avoiding any unnecessary price negotiations.
Sample Questions
 The Earth’s rate of rotation is constantly decreasing, causing the day to increase in duration. In the year 2000 the Earth takes about 0.548 s longer to complete 365 revolutions than it did in the year 1900.
 (a) What is the average angular acceleration of the Earth?
 (b) If this average acceleration remains constant, in what year will the Earths rotation come to rest?
1. Can you show me step by step how to solve this problem?:
 A spherical balloon is made from a material whose mass is 3.00kg. The thickness of the material is negligible compared to the 1.5m radius of the balloon. The balloon is filled with helium (He) at a temperature of 305degrees K and just floats in the air, neither rising nor falling. The density of the surrounding air is 1.19kg/m^3. Find the absolute pressure of the helium gas
