The velocity of a vehicle is measured at two distinct points in time and found to be 30 m/s at 1.0 s and 10 m/s at 2.0 s. Find the acceleration (in m/s2) and initial velocity (in m/s) to complete the equation of motion for the velocity of the vehicle.

Question

v(t) = t +

Round your answers to the nearest whole number.

Answer 1

acceleration=changeInVelocity/time=(10-30)/(2-1) = -20m/s^2

vf=vi+at
10=vi-20*2
vi=50m/s
