Question

Tolong jawab semuanya
beserta cara nya

Answer 1

5. a. v (rata2) = Δr/Δt
=
=
= 10

b. misalkan t= 10 s= 100
v= =
v= 10
t= 15
s= v×t
= 15×10
150

6. a. OA= GLBB, AC= GLB, BC= GLBB
b. OA
Δv = 30-0 =30
a= Δv/t
= 1

AB
a= 0 karena tidak terjadi pertambahan kecepatan

BC
v= 30 m/s
t= 60
s= 30.60
= 1800

vt² = ² -2.a.s
0²= 30² - 2.a.1800
0= 900 - 2.a 1800
-2a.1800 = 900
-2a =
-2a =
a=
= -

yg lain nyusul

7. = 36 km/jam
= 10 m/s
a= 2 m/s²
t = 10/2 = 5 s yang di komentar salah

8. t = 3 s
a= 9,8
v= (integral) a
= 9,8 t
= 9,8 (3)
= 29,4

10. a= 2 m/s²
t= 3 s
a= Δv/t
Δv= a×t
= 2×3
6

= vt - Δv
=108 - 6
= 102 m/s

dah beres
