In:
A runner accelerates at 2 m/s2 from rest to his top speed in 5 seconds. What was his final velocity?
How far did he go while he was accelerating? Objective:
Objective: To practice the equation for displacement with constant acceleration.
Success criteria
To be able to solve velocity and acceleration problems Velocity and displacement Velocity and displacement with constant acceleration
Equations:
Velocity with constant acceleration: V2=V1 + at Displacement: Δd=V1t + ½ at2 A plane starting a rest at one end of a A plane starting a rest at one end of a runway undergoes a uniform acceleration of 4.8 m/s2 for 15 s before takeoff. What is its speed at takeoff? How long must the runway be for the plane to be able to take off? Homework faire
