The position of an object as a function of time is given by x = bt 2 - ct, where b = 2.0 m/s2 and c = 6.7 m/s, and x and t are in si units. what is the instantaneous velocity of the object when t = 4.1

The instantaneous velocity of the object when t = 4.1 is 9.7 .

Explanation:

Instantaneous velocity, v =

x =

v = = 2bt - c

At t = 4.1 s

v = 2 × b × 4.1 - c

b = 2.0

c = 6.7 ...(Given)

v = 2 × 2 × 4.1 - 6.7

v = 9.7

The instantaneous velocity of the object when t = 4.1 is 9.7 .

the answer is a. the yacht traveled from the dock north to the 200-meter marker in the bay in less than 5 minutes, giving the passengers several more hours to fish.

im doing peak rn so sry if its wrong

we need to know the time interval during which the force acts. impulse of force = momentum change
