a 2 [kg] box is attached
to two identical springs that are in their relaxed state
when the block is centered on the frictionless horizontal
floor. The box is pressed to the left and then was released
from rest as shown in the figure. If work done by the left
spring is 25 [J], what is the speed of the box
as it passes the center x = 0?
Each of the four engines can produce a power id 56megawatts.assuming no air resistance,how long would it take the plane to reach its cruising speed and altitude?assume the mass of the plane is constant. Give me Answer in minutes and to be one decimal place of accuracy.
A partly full paint can has 2.75 liters of paint left in it. What is volume of the paint in cubic centimeters?
A) 2.75 x 10-3 cm3 C) 275 x 10-3 cm3 E) 27.5 x 103 cm3
B) 2.75 cm3 D) 2.75 x 103 cm3
What will be the temperature change of 0.5 kg of water(c= 4200J/kg K) that loses 21000J.
A solid cylinder of radius 0:500[m] is wrapped with a massless string to simulate a
yo-yo. Holding the free end of the string stationary, the cylinder is dropped from a height
of 2:50 [m] from the ground. Right before it hits the ground, the cylinder was found to have
an angular velocity of 5:00 [rad=s]. Assuming that the string does not slip or stretch as the
cylinder descends and rotates, what is the angular acceleration of the cylinder?
A homogeneous triangular lamina has the vertices (0, 0), (3, 0) and (0, 3). Obtain the coordinates of the centre of mass of the lamina.
•QUEST A: Search for the tent “Hall of Mirrors” near the faculty of engineering and enter. Look for a light emitter, a piece of paper and pen, a rook chess piece and a converging mirror to answer this question: A rook chess piece is located 2.5 times the focal distance from the converging mirror. If f=5 cm and h_o=5.5 cm, determine the image characteristics (location, object, size, type). If you apply the same distance and location of the object in front of the diverging side of the mirror, what will be the characteristics of the image?
Using Green's theorem evaluate the integral: ∫C (y³dx + 3x³dy) where C is the contour along the circle x² + y² = 1 taken counter clockwise.

A wooden block weighing 2.8 kg stands on a flat surface. A bullet weighing 3 g was fired horizontally towards the block at a speed of 500 m / s, and after passing through the block it appeared on the other side moving at a speed of 210 m / s. Find the speed of the block immediately after the bullet exits. Ignore the friction between the block and the horizontal surface.
