Answer:
20.94 m/s
Explanation:
Recall that average velocity is defined as:
V = distance / time
Then, for our case:
V = 754 m / 36 sec = 20.94 m/s
U=10 m/s
v=30 m/s
t=6 sec
therefore, a=(v-u)/t
=(30-10)/6
=(10/3) ms^-2
now, displacement=ut+0.5*a*t^2
=60+ 0.5*(10/3)*36
=120 m
And you can solve it in another way:
v^2=u^2+2as
or, s=(v^2-u^2)/2a
=(900-100)/6.6666666.......
=120 m
Sorry I had the answer but it wont let me type numbers :(.:
Distance = speed x time
distance = 116 x 10
distance = 1160 m
