Q. What is an expression for , the position of mass I as a function of time? Assume that position is measured in meters and time is measured in seconds.
Q. The origin of a coordinate system is at the center of a wheel which rotates in the xy plane about its axis which is the z axis. A force F = 196 N acts at a +33.0° angle to the x axis, at the point x = 13.0 cm, y = 33.6 cm. Determine the magnitude and direction of the torque produced by this force about the axis?
A small boat is moving at a velocity of 3.35 m/s while it is accelerated by a river current perpendicular to the initial direction of motion. If current acceleration is 0.750 m/s^2, what will the new velocity of the boat be after 33.5 s.
A little cat, Bella, walks in a straight line, which we shall call the x axis, with positive direction to the right. As an observant scientist, you make measurements of her motion and construct a graph of the little feline's velocity as a function..
Concept to find certain type of electronic devices & circuits.
Design a circuit to control the temperature of a water bath at a set-point temperature of 85°C. Choose a resistive sensor and draw up a circuit that will provide control around the set-point.
Through 5 successive 1.04 min intervals, a runner moves at the following constant speeds: 0.405 km/min, 0.220 km/min, 0.160 km/min, 0.163 km/min, and 0.323 km/min. compute the total distance travelled and average speed.
Find out the minimum values of m1 and m2 such that the overlapping of the bright fringes will occur and find position of the overlap on screen.
A 9.0 Kg box of oranges slides from rest down a frictionless incline from a height of 5.0 m. A constant frictional force, introduced at point A, brings the block to rest at point B, 19 m to right of point A. What is the velocity of the box just be..
For this experiment you will require a stand, string, a paper or plastic cup, a nail, a roll of paper towels or similar sized paper, coloured sand, or some other dry powdery product, and a ruler or measuring tape.
To which, according to the rotational analog of Newton's second law, is the angular acceleration experienced by an object directly proportional?
A dolphin in seawater at a temperature of 25 °C makes a chirp. How much time passes before it hears an echo from the bottom of the ocean, 208 m below.
A man pushes a lawn mower on a level lawn with a force of 186 N. If 35 percent of this force is directed downward, how much work is completed by the man in pushing the mower 6.5 m.
A 1245-N uniform beam is attached to a vertical wall at one end and is supported by a cable at the other end. A W = 1955-N crate hangs from the far end of the beam.
