a toy car starts from rest and accelerate uniformly at 2.0m/s square for 5.0 seconds. calculate its final velocity
I need an answer please
To calculate the final velocity of the toy car, you can use the equation:
v = u + at
Where:
v = final velocity
u = initial velocity (which is 0 m/s since it starts from rest)
a = uniform acceleration
t = time interval
Given values:
u = 0 m/s
a = 2.0 m/s²
t = 5.0 s
Substituting these values into the equation, we have:
v = 0 + (2.0 m/s²) × (5.0 s)
v = 0 + 10 m/s
Therefore, the final velocity of the toy car is 10 m/s.
the acceleration indicates how much the velocity changes each second. Hence,
v = at
(m/s) = (m/s^2)(s)
