Question

11. An object starts from rest accelerates uniformly 4 m/s2 for 4 minutes. calculate : (i) speed acquired (ii) distance travelled ​

Answer 1

Answer:

d = 1.152 × 10⁵ m

s = 960 m/s

Explanation:

u =0

a = 4 m/s²

t = 4×60 s = 240 s

distance = ut + 1/2 at²

= 0 + 1/2 × 4 × 240²

= 1.152 × 10⁵ m

speed acquired = u + at

= 0 + 4×240

= 960 m/s
