Conservation of Energy

In physics, the rule of the conservation of energy states that energy doesn’t disappear from the atmosphere; instead, it changes its form from one type to another. Energy is one of the most important physical quantities in nature, and it cannot be create…

Textbook Question

Chapter 11.1, Problem 11.20P

A spring AB is attached to a support at A and to a collar. The unstretched length of the spring is l. knowing that the collar is released from rest at x = x 0 and has an acceleration defined by the relation a = − 100 ( x − l x / a = − 100 ( x − l x / l 2 + x 2 ) , ) , determine the velocity of the collar as it passes through point C.

2. A car starts from rest and accelerates uniformly to a speed of 60 km/hour over a distance of 510 meters. (i) Calculate the acceleration and time taken. (ii) If a further acceleration raises the speed to 94 km/hour in 10 seconds, find the acceleration and further distance moved. (iii) The brakes are now applied and the car comes to rest under uniform retardation in 5 seconds. Find the retardation of the car and the distance travelled during this retardation.

Q6. As shown in the image below, two objects, A and B, are connected using the cable and pulley system. (The cable and pulley system is friction-less and weight-less.) If at this moment the acceleration of object Bis downward 2.3 m/s², determine the acceleration of object A (in m/s²2) at this moment. In this problem, downward motion is considered positive, and in your answer, negative sign must be included if the motion of A is upward. Please pay attention: the numbers may change since they are randomized. Your answer must include 1 place after the decimal point, and proper SI unit. A B VB

A box is moving in the i direction with a constant acceleration. A mass, suspended from the top of the box by a linear spring (unstretched length of zero), is moving to the right as well and isn't moving with respect to the box (the spring isn't changing in length and θ is constant). The force exerted by the spring on the mass is given by its spring constant k times its extension. For the present case, the spring is extended 5 cm from its rest length, k = 30 N/m and m = 0.15 kg. What is the angle θ equal to, and what is the acceleration of the box? You can solve for this without using the computer
