Question

pls answer these four questions plzzzzzzzzzzzzzz and I will the brainliest answer​

Answer 1

17(a). u = 0. t = 3 sec

g= 9.8

v= u + gt

v= 0+9.8 × 3

v = 29.4 m /S

(b). s= ut + 1/2 at ^2

s= 1/2 × 9.8 × 3×3

s= 9× 4.9

s = 44.1 m

18. u=0. a =4m/S

t= 10 sec

s = ut + 1/2 at^2

s = 1/2 × 4 × 10 ×10

s = 200 m

19. u= 56km/h

v= 58 km/h

t= 1/60 h

a= v-u / t

a= 58 - 56/ 1/60

a= 2×60/1

a= 120m/S square

19. s = d/t

s = 50/5

speed = 10m/S

bridge = 450 m

s = 10

time = d/S

t= 450 / 10

time = 45 sec

hey mate hope it helps you
