PLZ HELP ME FOR BRAINLIEST AND 100 POINTS

Find v(t), given acceleration a(t)=7j and initial velocity v(0)=k

Need asap ‼️ 20 pts which gravitational force field diagram is drawn correctly? (answers in pictures below)

The average time that it takes for the car to travel the first 0.25m is s. the average time to travel just between 0.25 m and 0.50 m is s. given the time taken to travel the second 0.25 m section, the velocity would be m/s.
