You are coasting on your skateboard at 1.4 m/s and you decide to speed up. if you accelerate at 05 m/s2 (square) for 7.0s what is your final speed?
0.5 or .05 ???
call it a
v = Vi + a t
v = 1.4 + a (7)
To find the final speed, we can use the formula: final speed = initial speed + (acceleration × time)
Let's break down the information given:
Initial speed (u) = 1.4 m/s
Acceleration (a) = 0.5 m/s²
Time (t) = 7.0 s
Using the equation, we can substitute the values:
Final speed (v) = 1.4 m/s + (0.5 m/s² × 7.0 s)
Final speed (v) = 1.4 m/s + 3.5 m/s
Final speed (v) = 4.9 m/s
Therefore, your final speed would be 4.9 m/s.
