8.2 A particle of mass m is projected with velocity V, up a plane of inclination 0° The
coefficient of friction between the particle and the plane is h By employing energy
balance, obtain an expression for the maximum distance s travelled up the plane
Find also the velocity

V2 of the particle when it returns to the point of projection

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?

In all trials, the magnitude of the final velocity for g1 + g2 was less than the magnitude of any initial velocity. as mass increased, what happened to the velocity? the velocity decreased. the velocity increased. the velocity of g1 + g2 could not be measured. the velocity was not affected by the mass increase.

Glass has a hardness that is in the middle of the hardness scale. what is the hardness of glass?
