Question

HURRY!

The three vehicles shown below are driving down the street at a constant velocity of 5 m/s. The blue car has a mass of 700 kg. The red car has a mass of 1800 kg. The silver pickup truck has a mass of 3500 kg. Annie-Drew wants to make a line graph showing the relationship between the kinetic energy and mass of the cars traveling at a constant velocity. What would the graph look like?

Answer 1

Explanation:

As the change in speed of both cars is zero therefore tangential acceleration of both cars will be zero .

now centripetal acceleration is given by

a=v2/r

where, r= radius and v= linear velocity ,

for blue car ab=302/r

for grey van ag =152/r

radius is same for both as they round the same turn ,

So, ab /ag = 30 2/15

2 =4 or a

b =4a/g
