Q. After driving a portion of the route, the taptap is fully loaded with a total of 25 people with an average mass of 60 kg per person. In addition, there are three 15 kg goats, five 3 kg chickens, and a total of 25 kg of bananas on their way to the market. Assume that the springs have somehow not yet compressed to their maximum amount. How much are the springs compressed?
Q. At a construction site, a 22.0 {rm kg} bucket of concrete is connected over a very light frictionless pulley to a 375 {rm N} box on the roof of a building. There is no appreciable friction on the box, since it is on roller bearings. The box starts from rest. Find the acceleration of the bucket.
A source emits sound uniformly in all directions. There are no reflections of the sound. At the distance r1 from the source the sound is 3.9 dB louder than it is at a distance r2 from the source. What is the ratio r1/r2.
A fuel leak is discovered at this point, and crew calculates that the plane can safely fly no more than 170 km before an emergency landing should be attempted. The only appropriate location for an emergency landing is 100 km north of their current po..
Speedboat A negotiates a curve whose radius is 118 m. Speedboat B negotiates a curve whose radius is 270 m. Each boat experiences the equivalent centripetal acceleration. What is the ratio vA/vB of the speeds of boats.
how is the graph of the total volume of a bathtub while the water inflow rate follows a seesaw pattern for half of the time and the similar pattern for outflows on the other half.
A 3 kg object id released from rest at a height of a 5 meter curved frictionless ramp. At the foot of the ramp is a spring force constant of k= 400n/m the object slides down the ramp and onto the spring compressing it to the distance x before comi..
A block of wood of mass 2 kg is suspended by long, light strings and is at rest. A bullet of mass 40 g, strikes and remains in the block, causing it to swing. The utmost height of the block above its rest position is 51 cm.
