A remote-controlled car is moving in a vacant parking lot. The velocity of the car as a function of time is given by υ⃗ =[5.00m/s−(0.0180m/s3)t2]i^ + [2.00m/s+(0.550m/s2)t]j^

a>

What is ax(t) the x-component of the acceleration of the car as function of time?

ax(t)=(−0.0180m/s3)t

ax(t)=(0.0360m/s3)t

ax(t)=(−0.0360m/s3)t

b>

What is ay(t) the y-component of the acceleration of the car as function of time?

ay(t)=2.00m/s2

ay(t)=0.550m/s2

ay(t)=(−0.550m/s2)t

c>

What is the magnitude of the velocity of the car at t = 6.59 s ?

Express your answer to three significant figures and include the appropriate units.

d>

Part D

What is the direction (in degrees counterclockwise from +x-axis) of the velocity of the car at t = 6.59 s ?

Express your answer to three significant figures and include the appropriate units.

e>
