2) An object is thrown directly upward with an initial speed of 25.0 m/s and returns along
the same path to its initial position.
Once thrown into the air, the only influence on the object is gravity, so we
can conclude that the acceleration acting on the ball is the one due to gravity g= 9.8 m/sec^2
a) Calculate how long will it take the ball to reach its peak (its maximum height).
b) Calculate the maximum height that the ball will reach.

An airplane flies eastward and always accelerates at a constant rate. at one position along its path it has a velocity of 34.3 m/s, it then flies a further distance of 40100 m and afterwards its velocity is 47.5 m/s. find the airplane\'s acceleration and calculate how much time elapses while the airplane covers those 40100 m.

Aturntable a is built into a stage for use in a theatrical production. it is observed during a rehearsal that a trunk b starts to slide on the turntable 10 s after the turntable begins to rotate. knowing that the trunk undergoes a constant tangential acceleration of 0.31 m/s2, determine the coefficient of static friction between the trunk and the turntable.
