If a shoe is dropped from a height of 40m what is its speed after falling for two seconds?
Regardless of the height from which it is falling, (neglecting air resistance) it's speed will be 19.62 metres per second. (Acceleration from gravity is 9.81 metres per second squared, so after 1 second it is moving at 9.81 metres per second and after 2 seconds it is moving at 19.62 metres per second.
How many kilometers does sound travel in seconds?
Use the standard equation for speed:distance = speed x time Solving for time: time = distance / speed
A baseball is seen to pass upward by a window 25M above the street with a vertical speed of 12ms if the ball was thrown from the street what was its initial speed?
for this problem use the formula V(final)= V0 +A*t V0=36ms V(final)= 12ms A= -9.8m/s^2 t=? plug into the equation 12= 36 + (-9.8)t -24= (-9.8)t t=2.4 seconds
What is the speed of a rocket that travels 8000 meters in 12 seconds?
8000m/12sec.
What is the speed of an object weighing 80 pounds dropped from 7 feet?
it strikes the ground at a velocity of 17.9 ft/s
A rock dropped on the moon will increase its speed from 0 its starting speed to 8.15 in about 5 seconds If you were standing on the moon measuring the rock's motion what would you measure?
That works out at an acceleration of 1.63 m/s2(Presumably you meant 8.15 meters per second.)You would measure how far the rock dropped in 5 seconds. Then you could work out the final speed (or acceleration) from the "equations of motion".
How do you find the height of the tower given only 8 seconds stone is dropped?
distance = speed x time so the distance is just the speed of the stone x 8 seconds
A rock dropped on the moon will increase its speed from 0 ms its starting speed when first dropped to 4.9 ms in about 3 seconds What value do you calculate for the magnitude of the acceleration o?
1.63 m/s2
If a car can go 0 to 60 mph in 8 seconds what would be its final speed after 5 seconds if its starting speed were 50 mph?
87.5mi/hr2
Suppose a rock is dropped off a cliff with an initial speed of 0 What is the rock's speed after 5 seconds in if it encounters no air resistance?
49
What is the speed of a ball that has dropped from a 100 m tall building when it reaches the ground in 4.5 seconds?
The speed is 44.4... repeating metres per second.
Suppose a rock is dropped off a cliff with an initial speed of 0 ms What is the rock's speed after 3 seconds in ms if it encounters no air resistance?
29.4
Suppose a rock is dropped off a cliff with an initial speed of 0 ms What is the rock's speed after 5 seconds in ms if it encounters no air resistance?

A marble dropped from a bridge strikes the water in 5 seconds. What is the speed with which it strikes and the height of the bridge?
Velocity final = vi + at = 49 m/s displacement = vi * t + ½2at² = 122.5 m vi = 0 a ≈ 9.8 t = 5
What is the final speed of the marble at the bottom of the straight ramp and loop ramp?
A marble traveling at 3.0m/s starts to acceleration at 4.5m/s over a distance of 25m. what is the final speed of the marble?
What is the final speed of a car that starts at 75 mph and decelerates at a rate of 10 mphsec for 5 seconds?
25mph
If a Rock is dropped off a cliff with an initial speed of 0 ms What is the rock's speed after 3 seconds in ms if it encounters no air resistance?
speed is decided by v = a(t), where t is your time variable and a is your acceleration constant. after 3 seconds, your velocity v = (9.8m/s2)(3s) = 29.4m/s
