Question

While entering a freeway, a car accelerates from a speed of 15.0 m/s at a rate of 2.11 m/s2 for 9.50 s. How far does the car travel in those 9.50 s? (To solve this part, first identify the unknown, and then discuss how you chose the appropriate equation to solve for it. After choosing the equation, show your steps in solving for the unknown, check your units, and discuss whether the answer is reasonable.) Enviar Respuesta Intentos Anteriores Incorrecto. Tries 5/40 What is the car's final velocity? Solve for this unknown in the same manner as in the previous part, showing al steps explicitly. ( Enviar Respuesta Tries 0/40

Explanation / Answer

a)

From Kinematic equations

S=Vot+(1/2)at2

S=15*9.5 + (1/2)*2.11*9.52

S=237.7 m

b)

From

V=Vo+at

V=15+2.11*9.5

V=35.05 m/s
