H = 1/2 g T2 = (4.9) (64) = 313.6 meters.

H = 1/2g T2 = (4.9) x (8)2 = 4.9 x 64 = 313.6 meters

What is the velocity of a ball in meters per second that drops from a roof and the speed was at 3.03 seconds?

If the ball was dropped from a roof and hit the ground 3.03 seconds later, then when it hit the groundits velocity was 29.694 meters (97.42 feet) per second (rounded) downward.


When acceleration occurs?

Acceleration occurs when velocity changes over time. The formula for it is as follows: a = (Vf - Vi) / t a: acceleration (meters/seconds2) Vf: Final velocity (meters/seconds) Vi: Initial Velocity (meters/seconds) t: Time (seconds)

A Kangaroo hops 60 m to the east in 5 seconds What is the kangaroo's velocity?

It's 60 divided by 5, Which is 12m/s east. Velocity is a vector for speed, since velocity has a direction and speed does not. Velocity has the SI units of meters per second. So you take the meters and divide by how many seconds to get your velocity.


If a trucks brakes are applied for 2 seconds giving it acceleration of -3.1 ms2 what will the trucks new speed be in ms?

No starting velocity was given, so I can't give a correct answer, but I can answer part of the question. Given an acceleration and a time through which an object accelerates, you can determine the change in velocity. Acceleration is just the change of velocity over a period of time. Since we have an acceleration of -3.1 meters per second squared, acting for two seconds, we have a change in velocity of -6.2 meters per second. Take the original velocity and subtract 6.2 meters per second to get the answer.
