5. A cycle accelerates from rest at a constant acceleration of 0.4m/s/s for 20 seconds then stops pedalling and slowed to standstill at constant deceleration over distance of 260m.
Calculate:
a. Distance travelled by cyclist in the first 20seconds
b. The speed of the cyclist at end of this time

oh my. I just had the answer in my head but its gone now

Explanation:

with 5 seconds, no, but over time if the police car stays at 65m/s ad the speeding car stays at 60, then obviously yes, but the answer to your question would be, no.

hope this : )

increasing transnational kinetic energy. because the transnational kinetic energy formula consists of only two variables, mass and velocity, increasing one of those properties is the only way to increase an object's transnational kinetic energy. increases to mass and velocity, however, do not have the same impact.
