A car travels 120 m in 5.0 s at constant velocity. If it then breakes and comes to a stop in 4.0 s what is the magnitude of its accerlation (assumed constant)?

#2) For this problem, ignore air resistance and assume the magnitude of the acceleration due to gravity is equal to 9.80 m/s². Let's also use up as the positive direction. Report answers to 3 sig figs. ECANSU (A) A rocket, initially at rest on the ground, accelerates straight upward from rest with constant net acceleration of 32.8 m/s2. The acceleration period lasts for a time of 3.47 s until the fuel is exhausted. Find the height the rocket reaches in the first 3.47 s. Show starting equations, algebra first, show final equations, numbers last. (B) After 3.47s, the fuel runs out and the rocket is now in free fall as it continues its motion. Find the total maximum height the rocket reaches as measured from the ground. Show starting equations, algebra first, show final equations, numbers last.

A cricket player accelerates the ball from a velocity of 5.5 m/s to 39 m/s in one direction.   If this shot takes 3.5 × 10-2 s, calculate the distance, in meters, over which the ball accelerates.

The smal archerfish Dength 20 to 25 cm) lives in brackish waters of Southeast Asia from India to the Philippines. This aptly named creature captures its prey by shooting a stream of water drops at an insect. either flying or at rest. The bug falls into the water and the fish gobbles it up. The archerfish has high accuracy at distances of 1.2 m to 1.5 m, and it sometimes makes hits at distances up to 3.5 m. A groove in the roof of its mouth, along with a curled tongue, forms a tube that enables the fish to impart high velocity to the water in its mouth when it suddenly closes its gill flaps. Suppose the archerfish shoots at a target that is 2.40 m away, measured along a line at an angle of 30.0° above the horizontal. With what velocity must the water stream be launched if it is not to drop more than 5.00 cm verticaly on its path to the target? 22.65 Your response is within 10% of the correct value. This may
