Nicholas is at the noah's ark amusement park and preparing to ride on the point of no return racing slide. at the top of the slide, nicholas (m=50 kg) is 28.5 m above the ground. determine nicholas' speed as he arrives at the bottom of the slide.

Explanation:

Recall that from the principle of conservation of energy,

P.E = K.E -------- eqn i

Solution

P.E = mgh

K.E =

i.e mgh = --------- eqn ii

m = 50 kg

v = ?

g = 9.8

h = 28.5 m

substitute for all values in eqn ii

50 X 9.8 X 28.5 =

13965 =

v = 23.635 m/s

Therefore, Nicholas arrives the bottom of the slide at a speed of 23.635 m/s
