Question 2 4 pts M A bullet of mass m=52 grams is fired vertically upwards into a wooden block of mass M = 4.1 kilograms. The block of wood (with the bullet lodged inside) rises to a height of 27 cm. What is the initial velocity of bullet? Give your answer in m/s to the correct number of significant figures. Hint: Remember your conversions to kilograms and meters!
You throw a ball vertically upward with an initial speed of 5 m/s from your dorm window... QUESTION 6 5 p You throw a ball vertically upward with an initial speed of 5 m/s from your dorm window. If the window is 10 m above the ground, find the time the ball is in flight. Give your answer with three significant figures and do not write the units. 5 p. QUESTION 7 Continuing with exercise 6, calculate the speed of...
A polo ball is hit with a mallet off the edge of a cliff. Its x- and y-coordinates as functions of time are given by x = 18.2t and y = 4.04t − 4.90t2, where x and y are in meters and t is in seconds. (Do not include units in your answer.) (a) Write a vector expression for the ball's position as a function of time (in m), using the unit vectors î and ĵ. (Give the answer in...
A golfer puts her golf ball straight toward the hole. The ball's initial velocity is 3.97 m/s, and it accelerates at a rate of -0.6 m/s2. What is the maximum distance that the golfer can be from the hole in order to make it? Give your answer in meters.
A golf ball is hit off a tee at the edge of a cliff. Its x and y coordinates as functions of time are given by x = 17.5t and y = 3.80t-4.90t. where x and y are in meters and t is in seconds (a) Write a vector expression for the ball's position as a function of time, using the unit vectors i and j.

a word using a quadratic equation with irrational. A ball is thrown from an initial height of 1 meter with an initial upward velocity of і5 m/s. The bars height h (in meters) after t seconds is given by the Find all values of t for which the ball's height is 6 meters (If there is more than one answer, use the "or" button.) height MacBook Ai
A Ball Hits a Wall Elastically Part A A ball of mass m moving with velocity strikes a vertical wall as shown in (Figure 1). The angle between the ball's initial velocity vector and the wall is 0, as shown on the diagram, which depicts the situation as seen from above. The duration of the collision between the ball and the wall is Δ, and this collision is completely elastic. Friction is negligible, so the ball does not start spinning...
Question 2 2 pts Given: I launch the ping pong ball at 7 m/sec off of a table that is 30 inches tall. If my angle at launch is 30° Find: What angle is the ball traveling at as it hits the floor? Note that this kind of calculation can be useful for design of the target. Give the answer in degrees and measured as a positive angle from the floor. D Question 3 2 pts Given: The system in...
