Step-by-step explanation:

Tackle this as you should for any quesiton. Write down a list of what you know and what you want to find.

u = 76 m/s

v = 98 m/s

t = 93 s

a = ?

Use the relationship that relates these four variables.

ie v = u + at, and solve for a

Look at all four equations of motion that you have learnt. They all involve four of the five variables. Become familiar with which one to choose based on what you want and what you have, also on what information is not required. In this case, the displacement is not required, and v = u + at is the only equation not involving displacement.

I’ve taken a bit of time, but you need a problem solving approach, and the subject of Applied Maths/Physics will get very difficult for you very quickly if you do not develop some strategies.
