An object is moving along a horizontal line such that it's velocity is V(t) : = What is the object's displacement between t = 0 and t = 5? O 1.558 O 1.944 2.558 O 2.944 3 (3t+4)*

A plane flying at an altitude of 20 km is at a direct distance D-4.0 + x from an airaort control tower, where xis the horizontal distance to the ldower If Uho plare's speed is 320 km/h, how fast is D changing when x=98 km? Ds changing at a rate of km/h. (Do not round untl the final answor Then round to the nearest ten as needed.)

The acceleration of an object (in m/s²) is given by the function a(t) = 6 sin(t). The initial velocity of the object is v(0) 11 m/s. Round your answers to four decimal places. a) Find an equation v(t) for the object velocity. v(t) = = b) Find the object's displacement (in meters) from time 0 to time 3. meters c) Find the total distance traveled by the object from time 0 to time 3. meters
