If an object with a mass of 100 g is in free fall What is the speed of the object after it has fallen for 4 seconds?
Neglecting air resistance, it will be 39.2 m/sec, regardless of the mass of the object. The acceleration due to gravity is 9.8 m/sec2 x 4 seconds = 39. 2 m/sec
How can you calculate the average speed of a moving object?
Distance divided by the time it takes to cover the distance, equals average speed per unit of time. For example: An object takes 0.5 seconds to cover 1 foot. 1 divided by 0.5 equals 2 (1/0.5=2) so it is traveling at an average speed of 2 feet per second.
Suppose an object in free fall is dropped from a building. Its starting velocity is 0 ms. What is the speed (in ms) of the object after falling 2 seconds Give your answer as a positive decimal.?
19.6 meters per second
A car runs at a constant speed on a circular track of radius 200 meters taking 62.8 seconds on each lapfind the average velocity and average speed on each lap?
Avg speed =dis/time=2(pi)*100/62.8=10m/s Avg velocity will be 0 since the car ends up back from where it is started ..
What is the acceleration from 0 to 2s?
-- Its magnitude is 1/2 of [ (the speed at 2 seconds) minus (the speed at zero) ]. -- Its direction is 1/2 of [ (the direction at 2 seconds) minus (the direction at zero) ].
How do you Determine the speed of an object that traveled 50 meters in 2 seconds?
Speed = (distance traveled) divided by (time to cover the distance) Speed = (50 meters) / (2 seconds) Speed = 50 meters per 2 seconds Speed = 25 meters per second
What is the speed of the object during the time interval from 4 seconds to 10 seconds?
2 m/s
What is the speed of an object that travels 10 meters in 5 seconds?
10 metres in 5 seconds; divide the distance by the time, 10/5= 2 metres per second
What is the average speed of an object traveling 2meters in 2 seconds then travels another 80meters duringthe next 40 seconds?
Th eobject traveled 82 meters in 42 seconds, so average speed is 82/42 = m/s = 1.95 m/s

Miles per hour in 6 tenths of a mile at 1.2 seconds?
An object traveling 0.6 miles in 1.2 seconds is traveling at a speed of 2 miles per second, which is 7200 miles per hour.
How fast are you travelling if you travel 10m in 2 seconds?
You are traveling 10 min 2 seconds. Therefore, you are traveling 5 m per second. (or 300 m per minute or 18,000 m per hour).

How do you find mass if you are given velocity force and speed?
force=mass x acceleration. you have force lets say 100N. you are given a velocity of lets say 10m/s at the first second. and you are given speed. if you are given one speed, then you are given the change in velocity (your acceleration). if you are given multiple speeds, then you can figure out your change in velocity of the amount of time the speeds are given as (also your acceleration). So lets say you are given a speed of 30m/s at the third second (second second sounds redundant). Assuming acceleration is constant as always, 30-10=20m/s over 2 seconds. So 20/2=10m/s2. now you have force and acceleration. 100= m x 10m/s2. m=10kg.
