Answer:
Vx = 6 m / s and .vy = 7 m / s
Explanation:
a) Let's substitute the value of time in the equations
x (1) = a +6
y (1) = b + 7
b) and e) We calculate the position for t = 2 s
x (2) = a +12
y (2) = b +14
We calculate the average speed
v = (x (2) -x (1)) / t2- t1
vₓ = ((a + 12) - (a-6)) / (2-1)
vₓ = 6 m / s
= ((b + 14) - (b-7)) / 1
= 7 m / s
c) and f) The instantaneous bone change calculates with the derivative
vₓ = dx / dt
vₓ = 6 m / s
That is constant for all time
= dy / dt
= 7 m / s
d) The speed on the x-axis is constant and is worth vx = 6 m / s
