... A block of mass 0.5 kg is pushed against a horizontal spring of negligible mass, compressing the spring a distance of ∆x as shown in the figure. The spring constant is 276 N/m. When released, the block travels along a frictionless, horizontal surface to point B, the bottom of a vertical circular tra ...

... Therefore, the average force acting on the ball is J = Favg ∆t −→ Favg = J/∆t 2.00m kg m/s Favg = 1.20×10−3 s = 1667m N (2) A ball having a mass of 150 g strikes a wall with a speed of 5.2 m/s and rebounds with only 50% of its initial kinetic energy. (a) What is the speed of the ball just after it l ...

... When a car rounds a comer at a constant speed, its acceleration is zero. As a ball falls freely, the distance it falls each second is the same. If you slide a hockey puck across a frictionless ice rink, there must be a horizontal force on the puck to keep it in motion. 5. Excluding the force due to ...

... The Goliath is a new wooden roller coaster that allows the riders to go upside-down on the loop shown below. The starting height of the coaster is 125. m. The radius of the loop is 25.0 m. Riders board the cars at A. The 2300-kg car is drawn by a chain up to the point B and then released from rest. ...

Circular Motion
... We know that Velocity = distance / time In circular motion, the distance traveled is all around the circle4 the circumference. The circumference = 2πr The time it takes the object to go all the way around the circumference once is called the period, T. So4 v = 2πr / T ...

Hunting oscillation
Hunting oscillation is a self-oscillation, usually unwanted, about an equilibrium. The expression came into use in the 19th century and describes how a system ""hunts"" for equilibrium. The expression is used to describe phenomena in such diverse fields as electronics, aviation, biology, and railway engineering.
