An automobile with an initial speed of 4.92 m/s accelerates uniformly at the rate of 3.2 m/s2 . find the final speed of the car after 4.5 s. answer in units of m/s. 008 (part 2 of 2) 10.0 points find the displacement of the car after 4.5 s.

19.32 m/s

Explanation:

Given

initial speed of car(u)=4.92 m/s

acceleration(a)=

Speed of car after 4.5 s

using equation of motion

v=u+at

v=19.32 m/s

Displacement of the car after 4.5 s

s=54.54 m

if you answer my question i will answer yours

at positions a, g kinetic energy is maximum.

at position d, potential energy is maximum.
