- How are instantaneous velocity and instantaneous speed related to one another? How do they differ?A monkey is locacted 12 m above you in a tree, you throw a ball upward with a speed of 20 m/s. At what time or times will the monkey be able to catch the ball? What will the velocity of the ball be at these times?Fast pls in 5 min i will give u like for sure
- Here’s an interesting challenge you can give to a friend. Hold a $1 (or larger!) bill by an upper corner. Have a friend prepare to pinch a lower corner, putting her fingers near but not touching the bill. Tell her to try to catch the bill when you drop it by simply closing her fingers. This seems like it should be easy, but it’s not. After she sees that you have released the bill, it will take her about 0.25 s to react and close her fingers—which is not fast enough to catch the bill. How much time does it take for the bill to fall beyond her grasp? The length of a bill is 16 cm.Pls fast and well explained I will rateYou 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 ease after (2.06)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 stone is dropped from a 85 meter high tower and at the same time another stone was thrown upward from the bottom of the tower at a velocity of 25 m/s. Hwow far will the two stones be from each other after three seconds?Hoping for complete solutions since I’m having a hard time with this. The question is asking for both an instantenous position x(t) and velocity v(t) equations. Pls skip if unsure or not willing to answer the subquestions A-E (these are all connected for one item). Thanks in advanced! Two blocks connected by a light horizontal rope sit at rest on a horizontal, frictionless surface. Block A has mass 15.0 [kg], and block B has mass m. A constant horizontal force F=80.0 [N] is applied to block A. In the first 3.00 [s] after the force is applied, block A moves 18.0 [m] to the right A. Draw the free body diagram of block A and Block B.Draw the x and y axis. (Hint: The string is taut all the time) B. What is the acceleration of block ? in the first 3.00 [s] if both blocks start from rest? C. From your answer in (b), write the acceleration of block B D. Write Newton’s 2nd law for block A along the horizontal direction and solve for the magnitude of the force exerted by the…You’re holding on to a helicopter that is 10 m above water.

- A meter stick is held vertically above your hand, with the lower end between your thumb and first finger. On seeing the meter stick released, you grab it with these two fingers. You can calculate your reaction time from the distance the meter stick falls, read directly from the point where your fingers grabbed it. Q: If the measured distance is 17.0 cm, what is the reaction time?Suppose you hold a Ping-Pong ball and a golf ball at arm’s length and drop them simultaneously. You’ll see them hit the floor at about the same time. But, if you drop them off the top of a high ladder, you’ll see the golf ball hit first. Explain.You are on the roof of a Physics Building, 48 m above the ground Your physics professorwho 1.95 m tall is approaching the building at constant speed 2.38 m/s If you wish to drop an egg on his headhow far should your professor be when you release the egg?
