kinematic question, i think it's hard:(
Two camels leave the spinx at time 52.5 s apart. The first moves off with a uniform acceleration of 1.30 m/s2, which it maintains for 1.92 s. It then continues with the acquired speed. The second camel moves of with a uniform acceleration of 1.45 m/s2, which it maintains for 2.84 s. It then contiues with the acquired speed. Claculate:
a) the distance they have both traveled when the second camel overtakes the first camel, which has walked in a straight line
b) the time taken by the second camel to catch the first.
a= v-u/t?? not sure..
s=ut+0.5at2
I really don't know how to put the 'two camels leave spinx at 52.5 seconds apart, i don't understand the 52.5 s apart and where to put that into equation. I'm pretty styumped with this question, could someone pls help? I have acceleration for both camels and the time but that's all i have. does u=0? Could i then use the equation s=ut+0.5at2 for each camel to find out their distances and then add them together. I just don't get the 52.5 seconds apart:(
and with question b) i know that the second camel has a greater acceleration than the first but other than that, i don't get it:(
