A 60 kg person runs up a 30° ramp with a constant acceleration. She starts from rest at the bottom of the ramp and covers a dist
Sladkaya [172]

We have that the instantaneous power is

P=1239.6W

From the question we are told that

A 60 kg person runs up a 30° ramp

distance of 15 m up the ramp in 5.8 s.

t = 4.0 s?

Generally the equation for the Force  is mathematically given as

F-mgsin\theta=ma\\\\F-60*9.8*sin30=60*a

Where

s=ut+1/2at^2\\\\15=+0.5*a*5.8^2\\\\\a=0.891\\\\

Therefore

F=60(0.891)+294\\\\F=347.5

Where

v=u+at\\\\v=3.567

Now

P=f*v\\\\P=347.50*3.567

P=1239.6W

the speed of a train is decreased in a uniform rate from 96 km/h to 48km/h through a distance of 800m. calculate the distance co
GREYUIT [131]

Answer:

1066.67 m

Explanation:

Given:

v₀ = 96 km/h = 26.67 m/s

v = 48 km/h = 13.33 m/s

Δx = 800 m

Find: a

v² = v₀² + 2aΔx

(13.33 m/s)² = (26.67 m/s)² + 2a (800 m)

a = -0.333 m/s²

Given:

v₀ = 26.67 m/s

v = 0 m/s

a = -0.333 m/s²

Find: Δx

v² = v₀² + 2aΔx

(0 m/s)² = (26.67 m/s)² + 2 (-0.333 m/s²) Δx

Δx = 1066.67 m

Round as needed.
