physics
Four identical masses of mass 800kg each are placed at the corners of a square whose side lengths are 15.0cm . What is the magnitude of the net gravitational force on one of the masses, due to the other three?

Physics
You are given a four-wheeled cart of mass 11 kg, where the distance between a wheel and its nearest neighbors is 2.1 m. Suppose we load this cart with a crate of mass 109 kg, where the crate's center of mass is located in the back-middle of the cart, 0.525 m from its cente...

Physics
If a frictionless incline has a difference in height from one end to the other of 19.5 cm and has a length along the incline of 1.36 m, find the time it takes for a block of 1.1 kg, starting from rest, to slide down the ramp from the top to the bottom of this incline.

physics
Sorry but that was wrong

physics
A 7 kg block is pushed by an external force against a spring with spring constant 124 N/m until the spring is compressed by 2.1 m from its uncompressed length (x = 0). The block rests on a horizontal plane that has a coefficient of kinetic friction of 0.7 but is NOT attached t...

Physics
How far x does it move down the incline before coming to rest? Suppose the incline is frictionless. The angle of inclination is 36 ◦ , the spring constant is 89.6 N/m the mass of the block is 9.05 kg and the acceleration of gravity is 9.8 m/s2 . Answer in units of m Choo...

Physics
A 6 kg block free to move on a horizontal, frictionless surface is attached to a spring. The spring is compressed 0.16 m from equi- librium and released. The speed of the block is 1.44 m/s when it passes the equilibrium po- sition of the spring. The same experiment is now repe...

A hot-air balloon is accelerating upward under the influence of two forces, its weight and the buoyant force. For simplicity, consider the weight to be only that of the hot air within the balloon, thus ignoring the balloon fabric and the basket. The hot air inside the balloon ...

the distance around a rectangular field is 340 yards. if the length of the field is 1120 yards, what is the width in yards?

physics
A 75.0 kN truck is parked in the middle of a 20.0 m long bridge. How much force must each end of the bridge exert to support the truck?

Physics
P = F/A But there are two tires. So the weight will be supported by the two tires, thus two areas. So P=F/2A, solving this, A = F/2P A = 600/2*6.7*10^5
