There are a bunch of new formulas That can be found by deriving Them from the two basic formulas That we already know.
Displacement with Constant Acceleration Δd = ½ (v i + v f )Δt
A racing car reaches a speed of 42 m/s. It then begins a uniform Negative acceleration, using its Parachute and brakes, and comes To a stop 5.5s later. Find how far The car moves while stopping. 120 m
Velocity with Constant Acceleration v f = v i + aΔt Displacement with Constant Acceleration Δd = v i Δt + ½a(Δt) 2
A plane starting at rest at one end Of a runway undergoes a constant Acceleration of 4.8 m/s 2 for 15s Before takeoff. What is its speed at Takeoff? How long must the Runway be for the plane to Take off? 72 m/s540 m
Final Velocity after Any displacement v f 2 = v i 2 + 2aΔd
A babysitter pushing a stroller Starts from rest and accelerates At 0.500 m/s 2. What is the Velocity of the stroller after it Has traveled 4.75 m? 2.18 m/s
Form to use when accelerating object has initial velocity. Form to use when accelerating object starts from rest. Δd = ½ (v i +v f )ΔtΔd = ½(v f )Δt v f = v i + aΔtv f = a(Δt) Δd = v i Δt + ½a(Δt) 2 Δd = ½a(Δt) 2 v f 2 = v i 2 + 2aΔdv f 2 = 2aΔd Equations for constantly Accelerated straight line motion
