1. A slug travelling at 3 mm/h,East decided to race the slug next to him increasing his velocity 5 mm/h,East in one hour.What was the slug's acceleration
Given
a = ?
V = 5 mm/h east
[tex] { \rm{V_0 = 3mm/h \: east}}[/tex]
t = 1 hr
Solution
[tex] { \tt{\frac{v - v _{0}}{t} }} = { \tt{\frac{5mm/h - 3mm/h}{1h} }} \\ [/tex]
[tex]{ \boxed{ \tt{a = 2mm/h² east}}}[/tex]
2. A driver starts his parked car within 5 seconds reaches a speed of 60 km/h as he travels east. What is the acceleration?
Given
a = ?
V = 60 km/h
[tex] { \rm{V_0 = 0 \: km/h \ east}}[/tex]
t = 5 s
Solution
[tex]{ \tt{\frac{v - v _{0}}{t} }} = { \tt{\frac{60km/h - 0km/h}{5s} }} \\ [/tex]
[tex]{ \boxed{ \tt{a =12 \: km/h² \: east}}}[/tex]
3. An object at rest started to travel at 10 m/s in 10 s ,what is the accelaration of an object?
Given
a = ?
V = 10 m/s south
[tex] { \rm{V_0 = 0 \: m/s \ south}}[/tex]
t = 10 s
Solution
[tex]{ \tt{\frac{v - v _{0}}{t} }} = { \tt{\frac{10m/s- 0 \: m/s}{10s} }} \\ [/tex]
[tex]{ \boxed{ \tt{a =1 \: k \: m/s² \: south}}}[/tex]
