Q. A 40kg child on a 2.30 m long swing is released from rest when the swing supports make an angle of 26 degrees with the vertical. The acceleration of gravity is 9.8 m/s2. If the speed of the child at the lowest position is 1.91047 m/s, what is the mechanical energy degenerate by the various resistive forces?
What is the magnitude of an average acceleration of the ball
A ladder 7.09 m long leans against the side of a building. If the ladder is inclined at an angle of 79.50° to the horizontal, what is the horizontal distance from the bottom of the ladder to the building.
A car of mass 1110 kg travels at a speed of 20 ms-1 along a straight road. The driver sees a red traffic light ahead, and applies brakes. The coefficient of friction between the car tyres and the road is 0.83. Take the acceleration due to gravity to ..
What is the highest height reached by the rocket. what is its initial speed as it leaves the ground.
The four tires of an automobile are inflated to a gauge pressure of 2.10E+5 Pa. Each tire has an area of 0.0267 m2 in contact with the ground. Find out the weight of the automobile.
A factory worker pushes a 30kg crate a distance of 4.50 meters along a level floor at constant velocity by pushing it downward at an angle of 30degrees below the horizontal. The coefficient of kinetic friction between the crate and the floor is 0...
A worker on a scaffolding 65 ft above the ground needs to lift a 390 lb bucket of cement from the ground to a point 30 ft above the ground by pulling on the rope weighting 2 lb/ft . Set up the integral of how much work is required (just give the i..

An astronaut on the Mars attaches a small brass ball to a 1.00- length of string and makes a simple pendulum. She times 13 complete swings in a time of 35.4 seconds. From this measurement she calculates the acceleration due to gravity on the Mars.
A group of hikers hear an echo 2.50 s after they shout. If the temperature is 28°C, how far away is the mountain that reflected the sound wave.
A person wearing a safety belt can withstand an acceleration of -3.0 x 10^2 m/s2. How thick must barriers be to safely stop a car that hits a barrier at 112 km/h.
IF Earth's orbit were suddenly to become much more eccentric. keeping orbital semimajor axis as is, fixed at 1 AU, but let's imagine shifting both the Earth's perihelion and aphelion points by 0.9 AU, so that at perihelion we were only 0.1 AU from th..
