Me with questions 1, 2 and 3.
i need a step by step explanation

1) d

2) 5 m/s

3) 100

Explanation:

The equation of position x for a constant acceleration a and an initial velocity v₀, initial position x₀, time t is:

(i)

The equation for velocity v and a constant acceleration a is:

(ii)

1) Solve equation (ii) for acceleration a and plug the result in equation (i)

(iii)

(iv)

Simplify equation (iv) and use the given values v = 0, x₀ = 0:

(v)

2) Given v₀= 3m/s, a=0.2m/s², t=10 s. Using equation (ii) to get the final velocity v:

3) Given v₀=0m/s, t₁=10s, t₂=1s and x₀=0. Looking for factor f = x(t₁)/x(t₂) using equation(i) to calculate x(t₁) and x(t₂):

muscle endurance

explanation:

i can do 50 in a row ( but i get so tired after that)
