aceleración= velocidad final - velocidad inicial ÷ el tiempo
a= 10-20÷5= -2 m/s
Answer:
<h3>The answer is 3.37 m/s²</h3>
Explanation:
The acceleration of an object given it's mass and the force acting on it can be found by using the formula
From the question
force = 172 N
mass = 51 kg
We have
We have the final answer as
<h3>3.37 m/s²</h3>
Hope this helps you
Answer:
2592 km/h
Explanation:
Given that a bullet is shot from a rifle with a velocity of 720 m/s. What is the velocity of the bullet in km/h.
The velocity = 720 m/s
Solution
To convert metres per second to kilometer per hour, you will multiply by 3600 and divide by 1000
720 × 3600/1000
720 × 3.6
72 × 36
2592 km/h
Therefore, the velocity of the bullet in kilometer per hour is 2592 km/h
