Problem 2: A student pushes a baseball of m = 0.18 kg down onto the top of a vertical spring that has its lower end fixed to a table, compressing the spring a distance of d = 0.14 meters from its equilibrium length. The spring constant of the spring is k = 740 N/m. Let the gravitational potential energy be zero at the position of the baseball in the compressed spring. Randomized Variables m = 0.18 kg k = 740 N/m d = 0.14 m
Estimate the penetration distance Ax of a small ball of radius r= 10-² m and density p 2650 kg/m³, thrown at a potential barrier at velocity v= 10 m/s. The height of the potential barrier is twice the kinetic energy of the ball. 10-28 m 10-30 m 10-32 m 10-34 m 10-36 m 10-90 m 10-40 m
In 1953, the US Army field-tested the M65 Atomic Cannon, capable of firing a W9 warhead (364 kg) at a velocity of 333 m/s, whereupon it exploded with energy of 15 kilotons of TNT. A) In the absence of air resistance, what is the optimal angle for firing the shell? Using your answer, how far would the shell travel? Assume the shell was launched and landed at the same height? B) How long was the shell in the air? C) What is the velocity (Magnitute and Direction) of the shell at the top of its trajectory?
(4) The scalar product is also useful for applications other than finding the work done by a force. The scalar product makes some problems that would otherwise be difficult relatively easy. Example: Suppose that the data from X-ray diffraction of a crystal indicates that the positions of the atoms in a molecule are as follows: The position of the carbon atom is C = 0i + 0f + 0k, the position of a neighboring oxygen atom is ö = 2î + 2j + k, and a hydrogen atom is located at H = -î + 2î – k. The oxygen atom and the hydrogen atoms are both bonded to the carbon atom. Distances are in nanometers (nm). a. What is the length ||Ō|| of the C-O bond? b. What is the length ||H|| of the C-H bond? c. What is the angle 0 between the C-0 and C-H bonds? You can solve this problem by taking the two ways to find the scalar product and setting them equal to each other, i.e., use the fact that 0 H = OH cos 0 = 0,Hx + 0,Hy+ 0,Hz.
(a) Compute the electrical energy used by a household whose monthly electrical bill is $40, computed at the rate of $0.05 per kWh. (b) How long could this energy be used to burn ten 100 W light bulbs? (c) If this energy were used to raise a car of mass 2100 kg, to what height would the car be raised?
