A 10-kg box is at rest on a horizontal frictionless surface, at the end of an unstretched horizontal spring with constant k=4000 N/m. The mass is then quickly struck with a hammer that imparts an impulse along the horizontal direction, compressing the spring a maximum distance of 38.73 cm.
(a) What is the speed of the box when it passes back through the equilibrium point?
(b) What is the maximum magnitude of acceleration of the box and
(c) where does it occur?
(d) What is the magnitude of the impulse that was imparted from the hammer to the box?
Petrus takes a cold glass of cola from fridge. He puts 3 cubes of ice into it. He laeves the glass on a table in a warm room for 5 minutes. He notices that the ice cubes have become smaller. The outside of the glass is now wet. What is the reason ..
Explain the distinction between reimbursement grants and entitlements. Explain how does this distinction affect the way each type of grant is accounted for?
The locomotive is moving at 25 km/h. The engineer of the high speed train immediately applies the brakes. What must be the magnitude of the resulting constant deceleration if a collision is to be just avoided.
Explain how much time will it take for the police officer to reach the speeder, assuming that the speeder maintains a constant speed?
You pull with a force of 295 N on a rope that is attached to the block of mass 20 kg, and the block slides across the floor at a constant speed of 1.2 m/s. The rope makes an angle of 35 degrees with the horizontal.
A 700 kg piston is initially held in place by a removable latch above a vertical cylinder. The cylinder has an area of 0.1 m^2; the volume of the gas within the cylinder is initially 0.1 m^3 at a pressure of 10 bar.
A car travelling at 19 {rm m/s} runs out of gas while travelling up a 21^circ slope. How far would the car go up the hill before it runs out of gas.
A 59.0 kg pole vaulter running at 9.5 m/s vaults over the bar. If the vaulter's horizontal component of velocity over the bar is 1.5 m/s and air resistance is disregarded, how high was the jump.
