40 m/s subtracted by 25m/s is 15.
15 has to be divided by the additional 3s which is 5
The 5 miles and the seconds left behind are 2
Answer: 5m/s2

Its acceleration is 5m/s2.
The formula for acceleration is Final speed - initial speed/time.
So 40m/s - 25m/s is 15m/s.
15m/s divided by 3s is 5m/s2.
Thus the acceleration is 5m/s2

What is the speed of an object that moves from 70 m to 68 m in 14 s?

PtichkaEL [24]

Speed = m/s
Velocity can be negative, but speed cannot.

70 - 68 = 2
2/14 = 0.143 m/s

action and reaction are equal in magnitude and opposite direction then why they don't balance each other

Harrizon [31]

Action and reaction are equal in magnitude and opposite direction by they don't balance each other because they don't occur on the same body. Action is involved on one body and reaction is involved on another body.

1.Convert 340 cm into m *(answer=0.34m)

Nataly [62]

Answer:

1.for the first one 100centimeters make 1 meter therefore

100cm-1m

340cm-x

340/100

=3.4

the answer is supposed to be 3.4, maybe there's a mistake with the question or the answer

2.the weight of a body is given by the formula

mass×gravity,in this case the mass is 75kg and the gravity is 9.8

weight=75×9.8

=735N

3.for this one the mass of a body is given by the formula

mass=weight/gravity

=420/9.8

=42.8kg

I hope this helps
