Q. Boxes A and B in the figure have masses of 14.4 {rm kg} and 3.3 {rm kg}, respectively. The two boxes are released from rest. What would be the speed of the boxes while box B has fallen a distance of 0.5m? The coefficient of kinetic friction between box A and the surface it slides on is 0.20. Make use of conservation of energy.
what is the ratio of the amplitude of the damped oscillations. You shoot a 58-g pebble straight up with a catapult whose spring constant is 310 N/m. The catapult is initially stretched by 0.20 m. How high above the starting point does the pebble f..
The displacement of a particle moving under uniform acceleration is some function of elapsed time and acceleration. Suppose we write this displacement as: s=ka^mt^n where k is the dimensionless constant.
A gymnast of mass 56.0 {rm kg} hangs from a vertical rope attached to the ceiling. You can ignore the weight of the rope and assume that the rope does not stretch. Use the value 9.81 {rm m/s^2} for the acceleration of gravity.
A tennis ball of mass 57 g travels with velocity m/s toward a wall. After bouncing off the wall, the tennis ball is observed to be traveling with velocity m/s.
define the effect of inertia on how far each can rolls.
A Norwich MCE student is involved in a crucial out of class experiment. He is in his dorm room 34 feet above an historic rock wall. Describe the final result and state any assumptions that you need to make. Would the final result be any different o..
A 1025 kg car carrying four 78kg people travels over a rough "washboard" dirt road with corrugations 4m apart which causes the car to bounce on its spring suspension.
What is the speed of the center of mass
Four or five gram blocks of metal are sitting out in the sun and absorb the same amount of heat energy. Use the following specific heat capacity data to resolve which block will increase its temperature the most.
A particle of mass m moves next to the x axis. Its position varies with time according to x=(3m/s^3)t^3-(4m/s^2)t^2.
Find the time it takes for a telephone call to go by way of satellite between these cities. Ignore the curvature of the earth.
A fisherman reels in 15.0 of line while landing a fish, using the constant forward pull of 35.0. How much work does the tension in the line do on fish.
