526.5m
Explanation:
Given parameters:
Acceleration = 3m/s²
Initial velocity = 21m/s
Final velocity = 60m/s
Unknown:
Displacement = ?
Solution:
To solve this problem, we apply the right motion equation which is shown below;
V² = U² + 2aS
V is the final velocity
U is the initial velocity
a is the acceleration
S is the displacement
Insert the parameters and solve;
60² = 21² + 2(3)S
3600 = 441 + 6S
3600 - 441 = 6S
3159 = 6S
S = 526.5m
