The velocity of car increases uniformly from 5 ms-1 to 10 ms-1, when it
travels 50m. Find acceleration of car.
Answers
Answer:
Acceleration is 0.75 m/s².
Explanation:
v = 10 m/s
u = 5 m/s
s = 50 m
v² = u² + 2as
=> (10)² = (5)² + 2 * a * 50
=> 100 = 25 + 100a
=> 100 - 25 = 100a
=> 100a = 75
=> a = 75/100
=> a = 0.75 m/s²
Acceleration is 0.75 m/s².
Given : The velocity of car increases uniformly from 5 ms-1 to 10 ms-1, when it travels 50m.
To Find : acceleration of car.
Solution:
Using the formula
V² - U² = 2aS
V = 10 m/s
U = 5 m/s
a = ?
S = 50 m
=> 10² - 5² = 2(a)(50)
=> 100 - 25 = 100a
=> 75 = 100a
=> a = 0.75 m/s²
acceleration of car. = 0.75 m/s²
