Extra Points because there are three questions.
1. An object goes from 20 m/s to 5 m/s in 1.2 seconds. What is the acceleration of the object?
a=vf-vi/t
2. What is the difference between distance and displacement? What is the difference between mass and weight?
3. What is the force necessary to accelerate a 40 kg object to 6 m/s/s?
F=ma

Ответ:
We will find the acceleration using the formula of force. The formula states that the net force applied on an object is directly proportional to the product of mass of the body and the acceleration of the body...
Where,
F is forceM is massA is accelerationIn our case,
F = 270 NM = 35 kgA = Unknown➪ Therefore, The acceleration of the body is 7.7 m/s²...~
