HElP a ball has a uniform acceleration of 4m/s .Assume the ball starts from rest determine the velocity and displacement at the end of 10s

A ball has a uniform acceleration of 4 m/s^2. Assume the ball starts from rest. How do you determine the velocity and displacement at the end of 10 s?

Why are antiviral mattress protectors a priority for health and safety?

A mattress protector or a mattress cover is essentially a bedding item made to encase your mattress to protect you and your sleep

You would do this using suvat equations.

From the information in the question:

S(displacement)= what we are finding

U(initial velocity)=0, as it starts at rest

V(final velocity)= what we are finding

A(acceleration)=4, given in question

T(time)=10, given in question

To find the final velocity,V, you can use the suvat equation V=U+AT

Therefore V=0+(4)(104

And V=40 ms^-1

Now you can use another suvat equation, to work out displacement, S.

V^2=U^2+2AS

Sub in your values

1600=8S

Divide both sides by 8, and S=200

not moving. pos accel,

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
