✬ Final Velocity = 200 m/s ✬
✬ Distance = 2000 m ✬
Explanation:
Given:
To Find:
Formula to be used:
Solution: Let the final velocity be v. Using the first formula to find final velocity
v = u + at
v = 0 + 10(20)
v = 200 m/s.
So, final velocity of car is 200 m/s.
[ To calculate distance use the second formula ]
s = ut + 1/2at²
s = 0(20) + 1/2(10)(20)²
s = 0 + 5(400)
s = 2000 m
So, Distance covered by car is 2000m.
✬ Final Velocity = 200 m/s ✬
✬ Distance = 2000 m ✬
Explanation:
Given:
Initial velocity of car is 0 m/s. ( Started from rest )
Acceleration of car is 10 m/s².
Time give is 20 seconds.
To Find:
What is the final velocity and Distance covered by car ?
Formula to be used:
v = u + at { for final velocity }
s = ut + 1/2at² { for distance }
Solution: Let the final velocity be v. Using the first formula to find final velocity
⟹ v = u + at
⟹ v = 0 + 10(20)
⟹ v = 200 m/s.
So, final velocity of car is 200 m/s.
[ To calculate distance use the second formula ]
⟹ s = ut + 1/2at²
⟹ s = 0(20) + 1/2(10)(20)²
⟹ s = 0 + 5(400)
⟹ s = 2000 m
So, Distance covered by car is 2000m.
