A pebble is dropped from rest from the top of a tall cliff and falls 4.9 m after 1.0 s has elapsed. How much farther does it drop in the next 2.0 s? (a) 9.8 m (b) 19.6 m (c) 39 m (d) 44 m (e) none of the above
Traumatic brain injury such as concussion results when the head undergoes a very large acceleration. Generally, an acceleration less than 800 m/s2 lasting for any length of time will not cause injury, whereas an acceleration greater than 1 000 m/s2 lasting tor at least 1 ms will cause injury. Suppose; a small child rolls off a bed that is 0.40 m above the floor. If the floor is hardwood, the childs head is brought to rest in approximately 2.0 min. If the floor is carpeted, this stopping distance is increased to about 1.0 cm. Calculate the magnitude and duration of the deceleration. In both cases, to determine the risk of injury. Assume the child remains horizontal during the fall to the floor. Note that a more complicated fall could result in a head velocity greater or less than the speed you calculate.
A ball is thrown upwards. Neglecting air resistance, what initial upward speed does the ball need to remain in the air for a total time of 10 seconds? Group of answer choices about 60 m/s about 50 m/s about 100 m/s about 110 m/s about 80 m/s
A student drove to the university from her home and noted that the odometer on her car increased by 16.0 km. The trip took 20.0 min.(a) What was her average speed?km/h (b) If the straight-line distance from her home to the university is 10.3 km in a direction 25.0° south of east, what was her average velocity?km/h (25° S of E) (c) If she returned home by the same path 7 h 30 min after she left, what were her average speed and velocity for the entire trip?average speedkm/h average velocity km/h
A steel ball is dropped onto a hard floor from a height of 1.50 m and rebounds to a height of 1.45 m. Calculate its velocity just before it strikes the floor. Answer in 2 decimal places. Calculate its velocity just after it leaves the floor on its way back up. Answer in 2 decimal places. Calculate its acceleration during contact with the floor if that contact lasts 8.00 × 10−5s.
An object is thrown with a horizontal velocity of 20 m/s from a cliff that is 125 m above level ground. If air resistance is negligible, the time that it takes the object to fall to the ground from the cliff is most nearly a 12 s b 3 s c 6 s d 25 s e 5 s
A kid in a wagon rolls from rest down a hill and reaches the bottom at 12 m/s. On the next run she gets a push and starts down at 5.0 m/s. At what speed does she now arrive at the bottom? (Hint: If you think it’s 17 m/s, think again!) 7 m/s 12 m/s 13 m/s 17 m/s
A stone is thrown vertically upward with a velocity of 96 ft/s from the top of the tower 112 feet high. (above the ground) Ignore , air resistance Determine the equation of motion s(t) of the stone if the point of reference is the ground. A. s(t) = - 16t2 + 96t + 112 B. s(t) = - 16t2 + 96t - 112 C. s(t) = - 32t2 + 96t + 112 D. s(t) = - 16t2 + 96t
