plzzz explain me your questions
Explanation:
While studying the velocity of a cheetah over time in a spreadsheet program is given by :
y = 2.2 x + 1.2 ...(1)
We know that,
v=v₀+at ...(2)
v₀ is velocity when t = 0, v is velocity after time t, a is acceleration and t is time.
If we consider time t on x-axis and v on y axis, then only we can draw a plot of equation (2). On comparing equation (1) and (2) we get :
a = 2.2 (but it is not correct as we don't know about axes).
Hence, the correct option is (a) "We cant tell without knowing what was plotted on the horizontal and vertical axes"
Answer:
Explanation:
The average speed is defined as:
Using the equations for uniformly accelerated motion, we calculate the runner's acceleration:
Now, we can calculate the distance that the runner travels:
Finally, we calculate the runner's average speed:
