In a TV set, an electron beam moves with horizontal velocity of 2.5 × 107 m/s across the cathode ray tube and strikes the screen, 40 cm away. The acceleration of gravity is 9.8 m/s2 .How far does the electron beam fall while traversing this distance?Answer in units of m.

Aspecial electronic sensor is embedded in the seat of a car that takes riders around a circular loop-the-loop ride at an amusement park. the sensor measures the magnitude of the normal force that the seat exerts on a rider. the loop-the-loop ride is in the vertical plane and its radius is 23 m. sitting on the seat before the ride starts, a rider is level and stationary, and the electronic sensor reads 740 n. at the top of the loop, the rider is upside down and moving, and the sensor reads 370 n. what is the speed of the rider at the top of the loop?

According to newtons universal law of gravitation, which would change the parh of the ball so it traces out widest curved path possible?

Agroup of students were investigating the force of gravity. they began by dropping a foam ball from a height of 3 meters into a bucket of sand. the ball hit the sand in 0.306 seconds. they dropped additional balls of approximately the same diameter, but of different masses. here is the data they collected. based on this experiment and the collected data, what would their conclusion be?
