Answer:

both train meet at 9.00 pm

Explanation:  

let t is the time after 1st train start  

we know distance = time * speed

D_1 = 40*t

D_2= 60*(t-3)                ( as second train depart after 3hr gap)  

we know

distance by one train = distance traveled by 2nd train i.e

D_1 = D_2

40*t=60*(t-3)  

40*t = 60*t - 60*3  

20*t = 180

t = 9  

hence both train meet at 9.00 pm

A boy twirls a 15-lb bucket of water in a vertical circle. If the radius of curvature of the path is 4 ft, determine the minimum
chubhunter [2.5K]

Answer:

11.35 m/s

Explanation:

Given,

Weight of the bucket = 15 lb

radius of curvature, r = 4 ft

Minimum speed of the bucket = ?

Using equation of centripetal acceleration

W=\dfrac{mv^2}{R}

15=\dfrac{\dfrac{m}{g}\times v^2}{4}

15=\dfrac{\dfrac{15}{32.2}\times v^2}{4}

v^2 = 128.8

v = 11.35\ m/s

Speed of the bucket  = 11.35 m/s
