Answer #1

The cat catches the mouse after 6 s. So they both gone the same distance in 6 s.

The mouse goes a distance = 3 × 6= 18 m

So the cat have to run 18 m.

    4. An antelope runs with a constant velocity of 22.0 ms- by a cheetah that is lying in the grass. The cheetah gets up and begins chasing directly after the antelope just as it has gone past, with a constant acceleration of 8.60 ms2, until it reaches its top speed of 30.0 ms-. At that point the cheetah runs with constant velocity. How far does the cheetah run before it catches up to the antelope?

    Two cars start from rest at a red stop light. When the light turns green, both cars accelerate forward. The blue car accelerates uniformly at a rate of 5.6 m/s2 for 3 seconds. It then continues at a constant speed for 7.8 seconds, before applying the brakes such that the car’s speed decreases uniformly coming to rest 178.16 meters from where it started. The yellow car accelerates uniformly for the entire distance, finally catching the blue car just as the...
