Which motor and body should Devon use to build the car with the greatest acceleration?
PilotLPTM [1.2K]

<u>Complete Question:</u>

Devon has several toy car bodies and motors. The motors have the same mass, but they provide different amounts of force, as shown in this table.  

The bodies have the masses shown in this table (refer attached figure).  

Which motor and body should Devon use to build the car with the greatest acceleration?

motor 1, with body 1

motor 1, with body 2

motor 2, with body 1

motor 2, with body 2

<u>Answer:</u>

Devon should build the car with motor 2 and body 1 for having the greatest acceleration.

<u>Explanation:</u>

As per Newton's second law of motion, the acceleration of any object is directly proportional to the force on the object and inversely proportional to the mass of the object.

It can be seen that motor 2 has greater force than the force provided by motor 1. Similarly, the mass of body 1 is found to be lesser compared to mass of body 2. So,

          acceleration =\frac{\text { Force }}{\text { mass }}

It gives, the system with motor 2 and body 1 the maximum acceleration. So the car should be built with motor 2 and body 1.

A 700 kg racecar slowed from 30 m/s to 15 m/s. What was the change in momentum?
xxMikexx [17]
Momentum equation is

change in momentum = mass•initial velocity•final velocity

so....

p=700(15) because your initial is 30, and your final in 15, so you subtract! hope that helped!
