Note: the 2 in the answers are exponents in a video game, a ball moving at 0.6 meter/second collides with a wall. after the collision, the velocity of the ball changed to -0.4 meter/second. the collision takes 0.2 seconds to occur. what’s the acceleration of the ball during the collision? use . a.) -1.0 m/s2 b.) 1.0 m/s2 c.) -5.0 m/s2 d.) 5.0 m/s2 e.) 0.24 m/s2

Final speed after collision with the wall

before collision the speed of ball initially

time taken for the collision

now as per the formula of acceleration we know that

now plug in all values in it

so acceleration is - 5 m/s/s for above situation

d₁ = displacement of tern from arctic to antarctic = 11000 miles

d₂ = displacement of tern from antarctic to arctic =   - 11000 miles

d = total displacement for the journey

total displacement for the journey is given as

d = d₁ + d₂

d = 11000 + (-11000)

d = 0 miles

t₁ = time of travel from arctic to antarctic = 3 months = 3 x 30 days = 90 days

t₂ = time of travel from antarctic to arctic = 3 months = 3 x 30 days = 90 days

t = total time of travel

total time of travel is given as

t = t₁ + t₂

t = 90 + 90

t = 180 days

average velocity is given as

average velocity = total displacement/ total time

v = d/t

v = 0/180

v = 0 miles/day
