Question

A space vehicle accelerates uniformly from 80 m/s at t = 0 to 170 m/s at t = 10.0 s .
How far did it move between t = 2.0 s and t = 6.0 s ?

Answer 1

Answer:464m

Explanation:

Acceleration (a)= (170-80)/10

a=9m/s²

S=ut+1/2 at²

S=80×2+1/2 ×9×2²

S=160+18

S=178m

S'=80×6+1/2×9×6²

S'=480+162

S'=642m

Distance travelled:- 642-178= 464m
