A car of mass 1200kg accelerates from rest at a rate of 2m/s^-2. Calculate how long it should take to reach a velocity of 50m/s.
V = Vo + a*t = 50 m/s.
0 + 2t = 50
t = 25 s.
Thanks Henry.
To calculate the time it takes for the car to reach a velocity of 50 m/s, we can use the equation of motion:
v = u + at
where:
v = final velocity (50 m/s)
u = initial velocity (0 m/s, since the car starts from rest)
a = acceleration (2 m/s²)
t = time
Rearranging the equation, we have:
t = (v - u) / a
Plugging in the given values, we get:
t = (50 m/s - 0 m/s) / 2 m/s²
t = 50 m/s / 2 m/s²
t = 25 s
Therefore, it would take 25 seconds for the car to reach a velocity of 50 m/s.
