You are assigned to do some calculations for a movie stunt that involves a car on a straight road. the road pictured above has a hill that rises 8.0 m above the flat region

Calculate the time it takes for the car to reach the beginning of the hill given that acceleration as already found in part a is 2.89 m/s²

5.88 s

Explanation:

Using kinematic equation, v=u+at where v and u are the final and initial velocities respectively, a is acceleration and t is time.

Considering the first part, acceleration is already found as 2.89 m/s and the final velocity is given as 17 m/s while the initial velocity is zero since it is at rest.

Making t the subject of formula then

t=(v-u)/a

Substituting the given figures then

t=(17-0)/2.89=5.8823529411764s

Rounded off, t=5.88 s

more than, less

less than, more

energy can be converted from one form to another, but it cannot be created or destroyed in ordinary chemical or physical means. do not understand what you are asking but hope this
