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 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
Suppose an object in free fall is dropped from a building Its starting velocity is 0 Ignoring the effects of air resistance what is the speed of the object after falling 3 seconds?
The speed of the object after falling for 3 seconds in free fall is 29.4 m/s.
What is the distance a free falling body travels from rest in ten seconds?
The distance a free-falling body travels from rest in ten seconds can be calculated using the formula for distance: d = 0.5 * g * t^2, where g is the acceleration due to gravity (approximately 9.81 m/s^2) and t is the time (10 seconds in this case). Plug in the values to find the distance traveled.
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 calculate speed in miles per second?
The distance travelled, measured in miles divided by the time taken, measured in seconds.
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.
How do you determine feet per second?
To determine feet per second, divide the distance in feet by the time in seconds it takes to cover that distance. The formula for calculating speed is Speed = Distance / Time. For example, if an object travels 60 feet in 10 seconds, the speed would be 60 feet / 10 seconds = 6 feet per second.
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).
In 2 seconds at 30 mph what is distance in feet?
At 30 mph, an object travels about 102.66 feet in two seconds.
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 far does a Car travel in 5 seConds at 25 mph?
25 mile in one hour one hour has 60*60 = 3600 seconds Therefore distance travelled in 5 seconds = (25/3600)*5= 0.0347222222222222 miles.
