Assuming you mean its range is 10m, then use the equation:
v0 = sqrt(r*g/sin(2θ)), where r is its range, θ is its initial angle, and g is acceleration from gravity.
=sqrt(10m*9.8m/s2/sin(90))
=sqrt(98.0m2/s2)
=9.9m/s

What unit is a wave's velocity measured in?
Meters per second
What will be the final velocity if the acceleration of 10 meters per second squared is sustained for 7 seconds?
It will depend upon the initial velocity of the body. If 'u' be the initial velocity of the body, then the final velocity will be: v = u + at (v = final velocity, a = acceleration, t = time) i.e., v=u+10*7 = (u + 70) m/sec. If u=0 (i.e the initial velocity be zero) then final velocity, v=70 m/sec.
What kind of mathematical relationship exists between velocity and distance?
the equation for average velocity a = s/t s = distance travelled t = time examples miles/hour, meters/sec
A hockey puck moves with velocity of 20 meteres per second If the friction of the ice retards the puck 1 meters per second squared How far will it go before it stops?
Using one of the three laws of mechanical motion : v2 = u2 + 2as, where v is the final velocity, u is the initial velocity, a is the acceleration, s is the distance. Then, 0 = 202 + 2 x (-1)s : 2s = 400 : s =200 meters. The puck will travel 200 meters.
How do you calculate range of projectile from ground at A degrees if you know its range is 200 meters if its launched from height of 2 meters at A degrees?
You cannot. You need to know either the initial speed or angle of projection (A).
If the launch angle is 15 degrees and the initial velocity is 50.0 meters per second what is the range?
If the initial velocity is 50 meters per second and the launch angle is 15 degrees what is the maximum height? Explain.
What is the initial velocity if you kick a rock off a bridge that is 450 meters high and it travels a horizontal distance of 32 meters before hitting the water below?
You kicked the rock with an initial velocity of 3.4 m/s.
An arrow in flight has an initial velocity of 65 meters per second and 10 seconds later it has a velocity of 35 meters per second Which is the acceleration of the arrow?
Acceleration of the arrow is -3m/s2A = (velocity minus initial velocity) / time
What object shoots upward with an initial velocity of 6 meters per second?
anything shot up with that initial velocity. There isn't anything in specific.
What is the formula for calculating the distance from the initial speed?
When you say initial speed I assume there will be accelleration. If so you could you: s = ut + 1/2at^2. or s = 1/2(u + v)t where s is distance in meters u is initial velocity in ms v is the final velocity in ms a is accelleration in ms^-2 t is time in s If there is no accelleration then s = ut
A person jumps off a diving board 4.0m above the water's surface into a pool the person's downward motion stops 2.0m below the surface of the water estimate the avg. decleration of the person under wa?
so what you need to do is find the velocity that the person enters the water and then use the equation v sub final squared = v sub initial squared + 2*acceleration(final distance-initial distance). final velocity is zero, find the initial velocity yourself and use 2 as the final distance where the initial distance is 0, solve for acceleration. Easy way: the decelleration would have been twice that provided by gravity because the diver decellerated to zero in half the distance of the dive. The diver starts at zero and hits max velocity in 4 meters then goes from max velocity to zero in 2 meters. 2 x 9.81 m/s2 = ___
How do you find velocity with a known time and distance?
Velocity equal distance divided by time. For example, an object that traveled 5 metes in 10 seconds had a velocity of 5/10 meters per second which is .5 meters per second. Velocity is speed in a direction. Sometimes a navigate or positive number is sufficient as the direction. Other times you will need to be more specific, such as .5 meters per second East or 1.3 meters per second 30 degrees East of North.
What is initial velocity measured in?
Initial velocity can be measured in the same units as any other velocity. In SI, that would be meters per second, but often km / hour are used, or (in a minority of countries) feet/second or miles/hour.
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)
Norma kicks a soccer ball with an initial velocity of 10.0 meters per second at an angle of 30.0 and Acirc and deg. If the ball moves through the air for 3.2 seconds what is the horizontal distance tr?
If it is kicked at 30 degrees to the horizontal then it will travel 27.7 metres.
Is there a difference between meters per second and meters?
Yes. The first is a speed (or velocity), the second is a distance.
What are the SI units for length speed and velocity?
Distance: Meters (or metres) Speed & velocity (meters per second). velocity also needs a direction but that isn't defined by SI units.
