A cheetah is running at a speed of 20.4 m/s in a direction of 79degree north...
Cheetahs can accelerate to a speed of 20.4 m/s in 2.50 s and can continue to accelerate to reach a top speed of 29.0 m/s. direction the cheetah runs. Express the cheetah's top speed brop in miles per hour (mi/h). Assume the acceleration is constant until the top speed is reached and is zero thereafter. Let the +x direction point in tho mi/h Starting from a crouched position, how much time facci does it take a cheetah to reach its...
A halfback is initially running south at a speed of 11.2 m/s, quickly cuts to his right, and 0.545 s later is running 60.0° west of south at 11.2 m/s. Find his average acceleration. Magnitude: direction ________ north of west.
A halfback is initially running south at a speed of 8.70 m/s, quickly cuts to his right, and 0.520 s later is running 60.0° west of south at 8.00 m/s. Find his average acceleration. magnitude direction north of west
A passenger on a moving train walks at a speed of 1.40 m/s due north relative to the train. The passenger's speed with respect to the ground is 4.5 m/s at an angle of 32.0° west of north. What are the magnitude and direction of the velocity of the train relative to the ground?
A running 61-kg cheetah has a top speed of 28 m/s. (a) What is the cheetah's maximum kinetic energy? J (b) Find the cheetah's speed when its kinetic energy is one half of the value found in part (a). m/s
An Australian emu is running due north in a straight line at a speed of 13.0 m/s and slows down to a speed of 9.40 m/s in 2.40 s. (a) What is the magnitude and direction of the bird’s acceleration? (b) Assuming that the acceleration remains the same, what is the bird’s velocity after an additional 1.00 s has elapsed?
An Australian emu is running due north in a straight line at a speed of 13.0 m/s and slows down to a speed of 11.0 m/s in 5.00 s. (a) What is the magnitude and direction of the bird’s acceleration? (b) Assuming that the acceleration remains the same, what is the bird’s velocity after an additional 2.80 s has elapsed?
While in a park, you walk west for 52 m, then you walk 35.0° north of west for 40 m, and finally you walk due north for 25 m. Find the components of your final displacement (in m), from your initial to final point, along the north and west directions. (a) find the displacement component due north
A 321-kg boat is sailing 10.0° north of east at a speed of 2.00 m/s. 30.0 s later, it is sailing 33.0° north of east at a speed of 4.10 m/s. During this time, three forces act on the boat: a 32.3-N force directed 10.0° north of east (due to an auxiliary engine), a 23.9-N force directed 10.0° south of west (resistance due to the water), and (due to the wind). Find the (a) the magnitude and (b) direction of...
A 250-m-wide river flows due east at a uniform speed of 2.8m/s. A boat with a speed of 7.7m/s relative to the water leaves the south bank pointed in a direction 31o west of north. What is the (a) magnitude and (b) direction of the boat's velocity relative to the ground? Give the direction as the angle of the velocity from due north, positive if to the east and negative if to the west.
