Answer:
speed is 2t - 5
velocity is 2t - 5
a = 2 m/s²
Step-by-step explanation:
Given the position of a particle expressed as:
s(t) = t^2 - 5t + 1
speed v = ds/dt
ds/dt = 2t - 5
Hence the speed is 2t - 5
velocity can also be expressed as the speed, hence, velocity is 2t - 5
Acceleration is the change in velocity with respect to time. Hence;
a = dv/dt
a = 2 m/s²
