In a 200m race Michael Jordon accelerates during the first 4s to final velocity of 12m/s Using v = u+at calculate his acceleration assuming he starts from at rest

If a rabbit runs 678 m down the street in 457s, what will its speed be?

Block 1, of mass m1 = 3.90 kg, moves along a frictionless air track with speed v1 = 31.0 m/s. It collides with block 2, of mass m2 = 51.0 kg, which was initially at rest. The blocks stick together after the collision.
