Driving on T.V Highway on your way to La Espiga Dorada for some conchas, you miss your turn and hit the brakes; your velocity changes from 40 east m/s to 10 east m/s in 10 seconds. What is your acceleration?
Acceleration = (Final velocity - Initial velocity) / Time = (10 m/s - 40 m/s) / 10 s = -3 m/s²
Acceleration = (Final velocity - Initial velocity) / Time = (40 m/s - 10 m/s) / 10 s = 3 m/s²
Acceleration = (Final velocity - Initial velocity) / Time = (10 m/s + 40 m/s) / 10 s = 5 m/s²
Acceleration = (Final velocity - Initial velocity) / Time = (40 m/s + 10 m/s) / 10 s = 5 m/s²
Ash is competing in the Pokemon Gym challenge Pikachu is losing his gym battle against Onyx. Pikachu’s only hope is to use Quick Attack. What is Pikachu’s change in velocity if it accelerates at 10 m/s² in 2 seconds?
Change in velocity = acceleration × time = 10 m/s² x 2 s = 20 m/s
Change in velocity = acceleration / time = 10 m/s² / 2 s = 5 m/s
Change in velocity = acceleration × time = 10 m/s² × 2 s = 12 m/s
Change in velocity = acceleration × time = 10 m/s² × 2 s = 8 m/s
Master Chief is driving a Warthog to escape Halo after setting the Pillar of Autumn’s core into nuclear meltdown. His Warthog has a velocity of 80 m/s west and then comes to a stop in 4 s, so he can board a Pelican to escape. Calculate the Warthog’s acceleration.
Acceleration = (Final velocity - Initial velocity) / Time = (0 m/s - 80 m/s) / 4 s = -20 m/s²
Acceleration = (Final velocity + Initial velocity) / Time = (0 m/s + 80 m/s) / 4 s = 20 m/s²
Acceleration = (Initial velocity - Final velocity) / Time = (80 m/s - 0 m/s) / 4 s = 20 m/s²
Acceleration = (Final velocity - Initial velocity) / Time = (0 m/s - 80 m/s) / 2 s = -40 m/s²
Which runner had the fastest average speed?
Atalanta
Hermes
Daphne
Achilles
