Question

When straight line motion is being considered, speed is the same as velocity. When motion is just along a straight line, acceleration is along a straight line. Acceleration ( in a straight line ) = ( change of speed ) / ( change in time ) When the acceleration is constant, we can easily find the velocity acquired as a function of time. Velocity acquired = acceleration X time Note the units of acceleration are ( meters / sec) / sec or meters / (sec X sec). Note that acceleration may be either positive or negative. If a car increases its velocity from zero to 60 km/hr in 10 sec, its acceleration is Question 33 options: 3 km/hr/s or 0.8 m/s^2 (Note s^2 means seconds squared) 3km/hr/s or 50 m/s^2 6 km/hr/s or 1.7 m/s^2 6 km/hr/s or 100 m/s^2 60 km/hr/sec or 16.7 m/s^2 60 m/hr/sec or 100 m/s^2

Explanation / Answer

absolutly right, acceleration is constant, we can easily find the velocity acquired as a function of time. Velocity acquired = acceleration X time Note the units of acceleration are ( meters / sec) / sec or meters / (sec X sec). Note that acceleration may be either positive or negative. If a car increases its velocity from zero to 60 km/hr in 10 sec, its acceleration
