The acceleration of a motorcycle is given by ax(t)=At?Bt2, where A=1.50m/s3 and B=0.120m/s4. The motorcycle is at rest at the origin at time t=0. Calculate the maximum velocity it attains. Letters A and B are not allowed in the answer.

Two cannon balls weighing 18 kg and 24 kg are chained together and fired horizontally with a velocity of 165 m/s from the top of a 21-m wall. the chain breaks during the flight of the cannonballs and the 18-kg cannonball strikes the ground at t = 1.5 s, at a distance of 240 m from the foot of the wall, and 7 m to the right of the line of fire. determine the position of the other cannonball at that instant. neglect the resistance of the air.
