Which is (kQ1Q2) / d^2
Answer:
20 seconds
Explanation:
t = Time taken
u = Initial velocity
v = Final velocity
s = Displacement
r = Radius of robot = 0.5 m
= Angular acceleration = 2 rad/s²
Linear acceleration is given by
While speeding up time taken is 10 seconds
The time taken to slow down is 10 seconds
Total time the trial is rum is 10+10 = 20 seconds
