A man is out fishing with his daughter. They are initially sitting at opposite ends of their 3.00-m canoe, which has a mass of 6

0.0 kg and is at rest in the middle of a calm lake. The man and the daughter then carefully trade places. We will neglect any resistive forces between the canoe and the water.
A)

Use these numbers: the mass of the man is 75.0 kg, and the mass of the daughter is 25.0 kg.

How far has the canoe moved, once the man and his daughter have finished trading places? _______ m

Answer:

s = 0.9375 m (to the left)

Explanation:

We have to find the center of mass in every case

Xcm initial = (75Kg*0m+25Kg*3m+60Kg*1.5m)/(75+25+60)Kg = 1.03125m

Xcm final = (25Kg*0m+75Kg*3m+60Kg*1.5m)/(75+25+60)Kg = 1.96875m

Variation: S = 1.96875m - 1.03125m = 0.9375 m

A train moves from rest to a speed of 30 m/s in 32.0 seconds. What is its acceleration?​
kramer

Answer:

0.94m/s (squared)

Explanation:

a=change in velocity/time

a=v-u/t

a=32-0=32/32

a=0.94m/s (squared)

The acceleration of an object would increase if there was an increase in the
xxMikexx [17]

As per Newton's II law we know that

F_{net} = ma

here we know that

F_{net} = F_{ap} - F_f

so here we will have

a = \frac{F_{ap} - F_f}{m}

so here if we need to increase the acceleration we need to increase the applied force while on increasing the mass or on increasing the friction force the acceleration will decrease.

So here correct answer will be

<em>A) force on the object.</em>

Fiora starts riding her bike at 18 mi/h. After a while, she slows down to 12 mi/h, and maintains that speed for the rest of the
lord [1]

Answer:

t = 2.5 hours

Explanation:

given,

speed of the bike for t time= 18 mi/h

final speed of the bike after t time = 12 mi/h

total distance, D = 69 miles

total time, T= 4.5 hour

time for which speed of the bike is 18 mi/h = ?

we know distance = speed x time

now,

18 x t + 12 (4.5 - t) = 69

6 t + 54 = 69

6 t = 15

t = 2.5 hours

The bike was at the speed of 18 mi/h for 2.5 hours.
