You're an investigator for the National Transportation Safety Board, examining a subway accident in which a train going at 90 km/hkm/h collided with a slower train traveling in the same direction at 24 km/hkm/h . Your job is to determine the relative speed of the collision, to help establish new crash standards. The faster train's "black box" shows that it began negatively accelerating at 2.1 m/s2m/s2 when it was 52 mm from the slower train, while the slower train continued at constant speed. What do you report ?
A ball is thrown upward from the edge of a cliff initial speed of 6 m/s (a)how fast is it moving .5seconds later in what direction? (b) how fast is it moving two seconds later in what direction? (Consider upward as + and downward as - v1 +6 m/s and g equal to -9.8 m/s)
A rescue helicopter is hovering over a person whose boathas sunk. One of the rescuers throws a life preserver straightdown to the victim with an initial velocity of 1.40 m/s andobserves that it takes 1.8 s to reach the water. (a) List theknowns in this problem. (b) How high above the water wasthe preserver released? Note that the downdraft of thelife preserver, so that an acceleration equal to that of gravityis reasonablehelicopter reduces the effects of air resistance on the falling
www Q3: As shown in figure, find that at what distance body A will attain a velocity of 3 m/s when starts from rest. 2000 N DOM N 00S
A uniformly accelerated body takes 10 s to cover 500 m. Assuming that the body starts from rest, find (a.) its acceleration and (b.) the time it will take to cover the next 500 m.
The brakes are applied to a moving car, causing it to uniformly slow down. While slowing, it moves a distance of 40.0 m in 7.00 s to a final velocity of 2.05 m/s, at which point the brakes are released. (a) What was its initial speed (in m/s), just before the brakes were applied? i have tried so many ways to solve this and i cant please explain
A woodpecker’s brain is specially protected from large accelerations by tendon-like attachments inside the skull. While pecking on a tree, the woodpecker’s head comes to a stop from an initial velocity of 0.600 m/s in a distance of only 2.00 mm. (a) Find the acceleration in meters per second squared and in multiples of g , where g=9.80m/s2 . (b) Calculate the stopping time. (c) The tendons cradling the brain stretch, making its stopping distance 4.50 mm (greater then the head and, hence, less acceleration of the brain). What is the brain’s acceleration, expressed in multiples of g ?
Unreasonable results Dragsters can actually reach a top speed of 145.0 m/s in only 4.45 s. (a) Calculate the average acceleration for such a dragster. (b) Find the final velocity of this dragster starting from rest and accelerating at the rate found in (a) for 402.0 m (a quarter mile) without using any information on time. (c) Why is the final velocity greater than that used to find the average acceleration? (Hint: Consider whether the assumption of constant acceleration is valid for a dragster. If not, discuss whether the acceleration would be greater at the beginning or end of the run and what effect that would have on the final velocity.)
In a 100-rn race, the winner is timed at 11.2 s. The second-place finisher’s time Is 11.6 s. How far Is the second-place finisher behind the winner when she crosses the finish line? Assume the velocity of each runner is constant throughout the race.
The speed of a bullet as it travels down the barrel of arifle toward the opening is given by v ! (- 5.00 x10*7)t*2+(3.00 x10*5)t, where v is in meters per second and t is inseconds. The acceleration of the bullet just as it leaves thebarrel is zero. (a) Determine the acceleration and positionof the bullet as a function of time when the bullet is in thebarrel. (b) Determine the length of time the bullet is accelerated. (c) Find the speed at which the bullet leaves thebarrel. (d) What is the length of the barrel?
Motion with gravity Neglecting air resistance, the motion of an objectmoving vertically near Earth’s surface is determined by the acceleration due to gravity, which is approximately 9.8 m/s2. Suppose a stone is thrown vertically upward at t = 0 with a velocity of 40 m/s from the edge of a cliff that is 100 m above a river.a. Find the velocity ν(t) of the object, for t ≥ 0.b. Find the position s(t) of the object, for t ≥ 0.c. Find the maximum height of the object above the river.d. With what speed does the object strike the river?
A car traveling at 20m/s is attempting to drive up an icy hill. When it getsonto the hill, it is able to go 10 meters before it hits some ice and begins sliding. Assume the hillis a 10 degree incline. A. How far up the hill does the car travel before it starts to slide back down? Make sure toinclude the initial 10 meters in your final distance. B. If the car then slides all the way back to the bottom of the hill, what is its speed when itgets to the bottom? Assume it doesn’t gain traction back, so it is sliding with no frictionthe whole way down.
