Please help this is due at tomorrow at 8:30 Am 1.How far does object A travel?
2.How far did object B travel
3.Which object traveled a greater speed?
4 Calculate the average speed of object A
5.Calculate on average speed on Object B
6.What is the interval for distance?
7. What is the interval for time

a and c

c is 100% but i am confused in a

the minimum constant speed at which she can catch the train is 2.7 m/s

given:

acceleration = 0.6

time = 4.5 s

to find:

velocity = ?

formula used:

from 1st kinematic equation we get,

v = u + at

u = initial speed of train = 0 m/s

v = final speed of the train

a = acceleration of the train

t = time

solution:

from 1st kinematic equation we get,

v = u + at

u = initial speed of train = 0 m/s

v = final speed of the train

a = acceleration of the train

t = time

v = 0 + (0.6 × 4.5)

v = 2.7 m/s

the minimum constant speed at which she can catch the train is 2.7 m/s
