Question

a particle starts with initial velocity of 2.5m/s and accelerates uniformly at the rate of 0.5m/s2 (a)find the distance it travels in 2 seconds (b) how much time does it take to reach a velocity of 7.5m/s (c) how much distance does it cover in reaching 7.5m/s​

Answer 1

Answer:

1) 6m

2) 10 sec

3) 75 m

Explanation:

1)s= ut + 1/2 at^2

s= 2.5×2 + 1/2×0.5×4

s=6m

2) v=u+at

7.5 = 2.5+0.5×t

t=10sec

3) v=d/t

7.5= d/10

75m= d
