Question

A child on a swing has a speed of 5.5 m/s at the low point of the arc (see the figure below). 5.5 m/s2 How high (in m) will t

Answer 1

Answer #1

Solution)

According to Conservation of energy,

At the highest point,

PE= KE

mgh= 0.5*mv^2

9.8*h= 0.5*(5.5)^2

So, height, h= 1.54 m (Ans)
