Answer:
<h3>30m/s</h3>
Explanation:
acceleration is the change in velocity of a body with respect to time
a = v-u/t
v is the final velocity
u is the initial velocity = 10m/s
t is the time taken = 10s
a is the acceleration = 2m/s²
substitute the values into the formula
2 = v-10/10
cross multiply
20 = v-10
v = 20+10
v = 30m/s
Hence the velocity of the body after 10s is 30m/s
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"
