A small object of mass m= 30 kg slides down a spherical dome of radius R=12 m without any friction. It starts off at the top (polar angle θ=0) at zero speed. Use g=10 m/s2. What is the magnitude of the force (in Newton) exerted by the dome on the mass when it is at θ...

The range R=23^2*sin(2*42)/9.8=53.68m

physics
nice explanation. It should also be noted that the period and velocity are the same for any two points on earth through the tunnel. This concept is called "gravity train"

Physics
IT Shows us that the relationship between the distance and the time is linear and it tells us that the speed of the plane is constant

physics
A bead of mass m slides without friction on a vertical hoop of radius R . The bead moves under the combined action of gravity and a spring, with spring constant k , attached to the bottom of the hoop. Assume that the equilibrium (relaxed) length of the spring is R. The bead is...

A person is riding on a flatcar traveling at a constant speed v1= 15 m/s with respect to the ground. He wishes to throw a ball through a stationary hoop in such a manner that the ball will move horizontally as it passes through the hoop. The hoop is at a height h=4 m above his...

i guess the correct answer is 9.3 kg. but i dont know how to get this answer?

environmental science
you can figure out the impact they had on the world by looking it up online or finding it in encyclopedias/your science textbook/or if you have a freind and your in the same class or even learning the same thing you can call them up and ask.
