A. A toy car with a mass of 2.00kg is accelerating to the right across a level surface at 5.00m/s2. If the force to the left is 30.0N, what is the force to the right? B. If the force down is 19.6 N, what is the value of the Normal force?

2.25m/s

Explanation:

Average velocity is the change in displacement of a bod with respect to time;

Velocity = Δd/Δt

velocity = d₂-d₁/Δt

Given d₂ = 12m, d₁ = 3m and Δt = 4s

Substitute the given value into the fromula;

velocity = 12-3/4

velocity = 9/4

velocity = 2.25m/s

Hence the seal's average velocity for the swim is 2.25m/s
