Cars A and B are racing each other along the same straight road inthe following manner: Car A has a head start and is a distance D_Abeyond the starting line at t = 0. The starting line is at x=0. CarA travels at a constant speed v_A. Car B starts at the startingline but has a better engine than Car A, and thus Car B travels ata constant speed v_B, which is greater than v_A.
1)How long after Car B started the race will Car B catch up withCar A?
2)How far from Car B's starting line will the cars be when Car Bpasses Car A?
B)In this problem, you will apply kinematic equations to a jumpingflea. Take the magnitude of free-fall acceleration to be 9.80m/s^2. Ignore air resistance.
1)A flea jumps straight up to a maximum height of 0.450 m. What isits initial velocity v_0 as it leaves the ground?
2)How long is the flea in the air from the time it jumps to thetime it hits the ground?
