Smart VLR users come

what would the instantaneous velocity be at 7.50 seconds and how would i solve instantaneous velocity for other values?

edit: solved, thanks for help

atleast 2

search it online yw

solve it yourself

bros asking vlr.gg users math questions

bro taking physics

dx/dt = V so just x coordinate/time coordinate of the points

o7 no clue

The instantaneous velocity on a position vs time graph can be found by finding the slope of the line at any given point.

bro really asked a website with an aveage iq of sentinels lan appearances in the past 2 years

Instantaneous velocity is dx/dt which is the slope of the graph.
The answer is the slope of the graph at the required instant (t = 7.5).

slope at 7.5 = (0 - -5)/(8-7) = 5/1 = 5

assuming x is -5 at t=7 and x is 0 at t=8.

It depends on being able to read the value of x precisely from the graph. Assuming x to be -2 at 7.5 is also fine, but you'll get a different answer.

5

For instantaneous velocity at 7.5 seconds, find the point at which it is 7.5 second and find its gradient. Here from 7.5 seconds to 8 seconds it is a constant slope, so just find the gradient of that line.

MaTh Is NsFW???????????

bro is in calculus

average american who needs help of dawg eater's huh?

Idk of what instant it's asking the instantaneous velocity of but whatever it is just write the equation of line passing through that point and the slope of that line is your instantaneous velocity

Velocity is distance over time. Instantaneous velocity is the velocity at THAT specified moment (in your case, 7.5 secs). So just take what the y-coordinate is at 7.5 secs. Take that y-coordiate/7.5 secs. You have the answer

p.s. (rusty maths so maybe wrong)

v=dx/dt
since it is a (x vs t) graph , just find the slope of graph at the required time.
From img:
v= (0-(-2))(8-7.5) = 4
