Consider a grey squirrel falling from a tree to the ground. Use a coordinate system in which positive is downward for this problem. a) Find the squirrel’s velocity, in meters per second, just before hitting the ground when it falls from a height of 1.3 m. Ignore air resistance.  b) The squirrel softens its landing by bending its legs when it touches the ground, thereby stopping itself over a distance of 7.6 cm. Assuming a constant rate of deceleration, find the squirrel’s acceleration during this process, in meters per second squared.

A drowsy cat spots a flowerpot that sails first up and then down past an open window.The pot is in view for a total of 0.50 s, and the top-to-bottom height of the window is 2.00 m. How high above the window top does the flowerpot go?

A river has a steady speed of 0.300 m/s. A student swims upstream a distance of 1.00 km and swims back to the starting point. If the student can swim at a speed of 1.10 m/s in still water, how long does the trip take (swimming up and down in the current)?   If the water were still, by how much would the trip be longer or shorter? (Give a negative answer for a shorter trip.)

A river has a steady speed of 0.300 m/s. A student swims upstream a distance of 1.00 km and swims back to the starting point. If the student can swim at a speed of 1.50 m/s in still water, how long does the trip take (swimming up and down in the current)? If the water were still, by how much would the trip be longer or shorter? (Give a negative answer for a shorter trip.) Need Help? Read It 7. - DETAILS SERCP8 4.P.005. PRACTICE ANOTHER MY NOTES ASK YOUR TEACHER A bag of sugar weighs 4.00 lb on Earth. What would it weigh in newtons on the Moon, where the free-fall acceleration is one-sixth that on Earth? Repeat for Jupiter, where g is 2.64 times that on Earth. Find the mass of the bag of sugar in kilograms at each of the three locations. Earth kg Moon kg Jupiter kg

From point A located at the perimeter of a circular forest of diameter 30 km we want to reachthe farthest point B of the forest. There is a straight footpath BC passing through the forest. Through the trees we can walk with speed 3 km/h, along the pathway the speed of walking is 5 km/h. Find the shortest possible time needed to reach point B?

A hare and a tortoise compete in a race over a course 1.00 km long. The tortoise craws straight and steadily at its maximum speed of 0.200 m/s toward the finish line. The hare runs at its maximum speed 8.00 m/s toward the goal for 0.800 km and then stops to tease the the tortoise. How close to the goal can the hare let the tortoise wins in a photo finish? Assume that, when moving, both animals move steadily at their respective maximum speeds. Pls include figures and fbd.

A river has a steady speed of 0.650 m/s. A student swims upstream a distance of 1.00 km and swims back to the starting point. If the student can swim at a speed of 1.50 m/s in still water, how long does the trip take (swimming up and down in the current)? sIf the water were still, by how much would the trip be longer or shorter? (Give a negative answer for a shorter trip.) s

An inquisitive physics student and mountain climber climbs a 51.0-m-high cliff that overhangs a calm pool of water. He throws two stones vertically downward, 1.00 s apart, and observes that they cause a single splash. The first stone has an initial speed of 2.06 m/s. (b) What initial velocity must the second stone have if the two stones are to hit the water simultaneously?

A river has a steady speed of 0.650 m/s. A student swims upstream a distance of 1.00 km and swims back to the starting point. If the student can swim at a speed of 1.50 m/s in still water, how long does the trip take (swimming up and down in the current)? Your response differs from the correct answer by more than 10%. Double check your calculations. sIf the water were still, by how much would the trip be longer or shorter? (Give a negative answer for a shorter trip.)
