Question

the speedometer reading of a car are shown below find the acceleration of a car and its displacement time 9:25 a.m. 9:45 a.m. speedometer 36 km per hour and 72 km per hour

Answer 1

u=36=36*5/18=10m/s
v=20m/s(after doing the same as abve)
time=45-25=20
20 min to sec=1200 sec
acc=(20-10)/1200=1/120m/s
distance=(v2-u2)/2a
distance=(400-100)/(1/60)
=300*60=18000metre
