Ten seconds after starting from rest an object on earth falling freely downward will have a speed of about what?

Answer 1

It depends on how long it has been falling and how far it fell. Use equations: [change in] v = a * t [change in] y = v [initial] * t + 1/2 * a * t^2 ----- v = velocity (in m/s) a = acceleration (in m/s^2); for free fall, it's 9.81 m/s^2 t = time (in s) y = vertical displacement (in m)

Answer 2

If we assume an acceleration by gravity of 9.82 meters / second2, or 9.82 (meters / second) / second, in 10 seconds you multiply that with 10: 98.2 meters / second.

Answer 3

A distance a free falling object will fall is given by physics formula: y=f(x)=16x^2, distance of y feet in x seconds.

So, the distance covered in x=10 seconds would be (insert in formula), f(10)=16*(10)^2= 1600 feet.

Answer 4

take g = 9.8 (m/s)/s

u = 0

v = 10 m/s

then t= v/g = 10/9.8 = 1.02 seconds

then s = (g*t^2) / 2 = (9.8*1.02*1.02) / 2 = 10.196 metres

actually its 10.196/2 = 5.098 metres

Answer 5

Acceleration of gravity (near the earth's surface) = 9.8 meters per second2

Final speed = (10 x 9.8) = 98 meters per second

Initial speed = 0

Average speed = 1/2 (0 + 98) = 49 meters per second

Distance = 49 x 10 = 490 meters

Answer 6

v = v0 + at

since the only acceleration is due to gravity

v = v0 + gt

v = 0 (dropped so no initial velocity) + 9.8 * 10

v = 98m/s

Answer 7

instantaneous speed: 100 m/s

average speed: 50 m/s

distance fallen: 500 meters

Answer 8

Assuming on Earth,

* g = 9.8 m/s2

* t = 10 s * u = 0 m/s (as body starts from rest) v = u + gt

v= 0 + 9.8 x 10 v = 98 m/s

Answer 9

If we assume an acceleration by gravity of 9.82 meters / second2, or 9.82 (meters / second) / second, in 10 seconds you multiply that with 10: 98.2 meters / second.

Answer 10

98 m/s.
