I had a dream last night that I was chased by my teddy bear. In my dream, I was sleepwalking at a constant velocity of 60ft/sec. At exactly 4:00 am I noticed my teddy bear standing 1000 feet behind me. At that instant I began to accelerate at 10 ft/sec/sec and the teddy bear began to accerlate after me at 12 ft/sec/sec. At the moment the bear caught up to me, I woke from my dream in a cold sweat. To the nearest second, What time was this?
You stand on a top of a lighthouse while your friend is on the ground outside. You peered into the window and dropped the bulb used on the lighthouse and asked your friend to check if it is still okay. He caught the bulb with the ease after 2.49 seconds then tossed it back up to you and it lands directly into your hands. What is the velocity of the bulb at the exact moment your friend tossed it back up to you?
A cat is sleeping on the floor in the middle of a 3.0 m wide room when a barking dog enters with a speed of 1.50 m/s. As the dog enters, the cat immediately accelerates at 0.85 m/s2 toward an open window on the opposite side of the room. The dog is a bit startled by the cat and begins to slow down at 0.10 m/s2 as soon as it enters the room. How far is the cat in front of the dog as it leaps through the window?

Bob then put the ring on Alice’s finger. Alice was very happy. She threw her hands up in the air. Unfortunately, the ring slipped from her finger and fell down due to gravity.Bob set up a camera to record the moment. Thus, he look at the footage and determine that the ring was going out of Alice’s hand with speed of vi =10m/s at an angle of θ=30 . The dimension of the building is given below. (a) If the ring were to land on the terrace, how long would it take?(b) If the ring were to land on the Lawn, how long would it take?(c) Where should Bob search for the ring? Terrace or lawn? An answer with no support reasoning will recieve no credit.arrow_forwardA runner and a cyclist compete in a race over a straight course 20 km long. The runner runs at a steady speed of 10 m/s toward the finish line. The cyclist zips at a speed of 23 m/s toward the finish line for 12 km but upon seeing that he is already far ahead of the runner, he decides to stop and wait for the runner to catch up to him. The runner eventually reaches the cyclist and continues moving toward the finish line. The cyclist waits for a while after the runner passes and then cycles toward the finish line again at 23m/s. Both the cyclist and the runner cross the finish line in the exact same instant. Assume both of them, when moving, move steadily at their respective speeds. (a) How far is the runner from the finish line when the cyclist resumes the race? (b) For how long in time was the cyclist stationery?arrow_forward
- A jeepney and a train are moving together along parallel paths at 30.0 m/s, with the jeepney adjacent to the rear of the train. The jeepney driver sees the traffic light turn red, so he accelerates at -2.50 m/s2, and then let his jeepney come to rest. The jeepney is at rest for 50.0 s, and then accelerates at 2.50 m/s2 to go back to a speed of 30.0 m/s. Assuming that the speed of the train remained constant at 30.0 m/s, how far is the jeepney from the rear of the train when the jeepney reaches a speed of 30.0 m/s?arrow_forward1.b.In Example 2.12, two circus performers rehearse a trick in which a ball and a dart collide. Horatio stands on a platform 7.8 m above the ground and drops a ball straight down. At the same moment, Amelia uses a spring-loaded device on the ground to launch a dart straight up toward the ball. The dart is launched at 16.0 m/s. Find the time and height of the collision by simultaneously solving the equations for the ball and the dart. (Due to the nature of this problem, do not use rounded intermediate values in your calculations—including answers submitted in WebAssign.)arrow_forwardAs a science project, you drop a watermelon off the top of the Empire State Building, 320 m above the sidewalk.

- You throw a ball straight up from a roof of a building. The ball leaves your hand at a point even with the roof railing with an upward speed of 15m/s. The ball is then in free fall. On its way back down, it just misses the railing. After 6.0s from release, the ball then hits the ground. What is the velocity of the ball upon impact on the ground? 198.5m/s -198.5m/s 352m/s -352m/sarrow_forwardMaria throws two stones from the top edge of a building with a speed of 12 m/s.
