How do you know an objects speed and velocity?
if the objects distance travelled and time is given then speed=distance/time eg- distance travelled 50 mtrs time taken 5 seconds speed 50/5 =10m/s velocity=u(initial velocity 0 for free falling objects) + at(acceleration x time)
How do you work out the speed of a moving car?
By finding the distance the car has travelled , in meters, in a specific time , in seconds , you get the speed of the car in meter per second Then , Speed = Distance Travelled/Time Taken
What is speed of a freely falling object ten seconds after starting from rest?
98 meters (322 feet) per second.
What does doubling the falling time of something affected by gravity do in terms of distance?
take g = 10 m/s^2 , u = 0 in all cases ,measured from same datum s=(10*t^2)/2 if t = 1 second then s = 5 metres if t = 2 seconds then s = 20 metres (2* time = 4*distance) if t = 3 seconds then s = 45 meters (3* time = 9*distance) if t = 4 seconds then s = 80 meters (4* time = 16 * distance) but distance travelled between secs metres 0-1.......5 1-2.... 15 2-3.... 25 3-4..... 35
Ten second after starting from rest a freely falling object will have the speed of about?
9.8 meters/second2 x 10 seconds = 98 meters/second.
How do you cancel out the seconds in meter per second?
Multiply by a value in seconds, that way you find out the distance. The distance will be in metres which will be travelled in a certain amount of seconds

How do you determine feet per second?
distance travelled (feet) / time taken (seconds)

How do you calculate speed in miles per second?
The distance travelled, measured in miles divided by the time taken, measured in seconds.
Can a position time graph be created from a velocity time graph?
Distance travelled from a velocity / time graph can be calculated from area under graph, say area under (v/t) graph from 0 - 1 seconds = distance travelled after 1 second, then do 0 - 2 seconds, 0 - 3 etc for set of data for distance / time graph
A ball of mass 5 kilograms begins falling with gravity of 10 meters per second squared. How many meters does it fall in 7 seconds?
Mass doesn't affect this equation, if its falling from rest at an acceleration (a) of 10 m/s2 the distance travelled (s) in 7 seconds (t) is resolved by the equation: . s = 0.5 * a * t2 s = 0.5 * 10 * 49 s = 245 metres
How far would you travel if going 20 kilometers per second?
It depends on how long (time) you are travelling at 20 kilometres per second. Distance = speed x time Say you travelled for 10 seconds then your distance travelled will be 200 km. Every one minute (60 seconds) you will travel 1200 km.
What is the distance covered by a freely falling object 5 seconds after it is dropped from rest?
0.7848 meter
In terms of distance what is a million million units?
It depends on what it of distance is being used. A million million kilometres is 6684 astronomical units, which is the distance travelled by light in 3.3 million seconds, or 5½ weeks.
Train is135m long average speed 120 kmh 50 seconds it passes through tunnel what is the length of the tunnel?
120 km/h = 120,000m/hr = 33.333 m/s Distance travelled in 50 seconds = 33.333 * 50 = 1666.666 metres Tunnel length = distance travelled - train length - 1666.666 - 135 = 1531.666metres
The distance s meters traveled by a falling body starting from rest after time t seconds is?
If air resistance can be ignored, the distance in meters is 4.9t2. Note that 4.9 is half the numerical value of Earth's acceleration (9.8 meters per second square).
