Two forces act on a block of wood. The first force has a magnitude of 8.66 N in a direction 12.0 degrees counterclockwise from the positive x-axis. The second force has a magnitude of 3.57 N in a direction 354 degrees counterclockwise from the positive x-axis. What is the magnitude of the resulting force? At what angle (in degrees) does the resultant force point? (Give an answer between -180 degrees and + 180 degrees counterclockwise from the positive x-axis.)
The Space Shuttle travels at a speed of about 7.60 103 m/s. The blink of an astronaut's eye lasts about 120 ms. How many football fields (length = 91.4 m) does the Shuttle cover in the blink of an eye?
A stone takes 0.28s to travel past a window 2.2m tall. From what height above top of the window did the stone fall?
A 60 kg person drops from rest a distance of 1.20m to a platform of negligible mass supported by a stiff spring. The platform drops 6cm before the person comes to rest.
The reflected sound is afterwards mixed with the transmitted sound, and 85 beats per second are detected. The speed of sound in body tissue is 1520m/s. compute the speed of the fetal heart wall at the instant this measurement is made.
A friend of yours is loudly singing a single note at 411 Hz while racing toward you at 25.5 m/s on a day when the speed of sound is 341 m/s.
Just before the collision and in kilometers per hour, what was the speed of the rocket piece relative to the satellite if both were in circular orbits and the collision was (a) head-on and (b) along perpendicular paths.
An airplane, whose air speed is 380 km/hr, is supposed to fly in a straight line 23.0 degrees north of due east. A steady 100 km/hr is blowing from the north. Illustrate in what direction should the plane head realative to the earth?
What is the greatest possible distance from the wall
A student (m = 56 kg) falls freely from rest and strikes the ground. All through the impact with the ground, he comes to rest in a time of 0.04 s.
An elevator and its load have a combined mass of 1600 kg. Find the tension in the supporting cable when the elevator, originally moving downward at 12 m/s, is brought to rest with constant acceleration in a distance of 28 m.
Blocks A and B are connected across a frictionless pulley by a cord of negligible weight. If block B lies on a horizontal, frictionless surface and block A hangs vertically, what can be said about the acceelration of block B?
