Answer:
Initial Velocity = 0 m/s
Final Velocity 24 m/s
Taken 4 seconds
Putting Values :
24 = 0+ a(4)
24 = 0 + 4a
24 = 4a
24 = 4a
a = 6 m/s
So, The Acceleration of the car is 6 m/s.
Three Equations Of Motion :
Here:
Velocity of a car started from rest reaches 24
To find:
Acceleration of the car.
Solution:–
Initial Velocity = 0 m/s
Final Velocity 24 m/s
Taken 4 seconds
Using 1st equation:
v = u + at
Putting Values :
⟹ 24 = 0+ a(4)
⟹ 24 = 0 + 4a
⟹ 24 = 4a
⟹ 24 = 4a
⟹ a=424
a= 6m/s
So, The Acceleration of the car is 6 m/s.
Three Equations Of Motion :
v = u+ at
S = ut + 1/2 at
v² - u² = 2as
Here:
v = Final Velocity
u = Initial Velocity
t = Time Taken
a = Acceleration
s= distance travelled
