PLEASE ANSWER THE QUESTION BELOW ASAP

Question:

Question 1 A velocity-time graph for the motion of a particle is shown below. Which of the following choices correctly ranks the accelerations of the particle at points A, B, and C (aA. aB, and ac)? VA B C A Oac > aB > aA OaA > ac > aB OaA > ap > ac Oag > ac > aA Oac > aA > aBQuestion 2 A rock is launched straight up from the ground. It rises to a distance 5.0 m and then returns to the ground. Neglecting air resistance, while the rock is in the air you know that: 0 the acceleration was upward on the way up and downward on the way down 0 the speed was zero at its maximum height, but the velocity was never zero 0 the velocity was constant except at the moment the rock turned around 0 the rock took longer to go up than to go down 0 the rock hit the ground at the same speed as it was launched Question 3 A tiger and a lion encounter each other in the jungle at a distance of 75.0 m. They decide to fight. If the tiger moves at 15.0 m/s and the lion moves at 8.00 m/s how much time elapses before they come into contact and fight? 7.51 s 10.7 s 9.34 s 3.26 s O 8.32 s
