Q1/ A balloon, rising vertically with a velocity of 16m /sec, releases a sandbag at an instant when the balloon is 64 m above the ground. (a) Compute the position and velocity of the sandbag at the following times after its release: 1 sec, 2 sec. (b) How many seconds after its release will the bag strike the ground? (c) With what velocity will it strike?

The tank is to be placed on a hill that is 1 km high above the ground. The enemy’s base is located at a horizontal distance of 10 km away and it is in a valley 0.5 km below the ground. Air resistance is neglected. Gravitational acceleration is constant and equal to 9.8?/?2 downwards. If the bomb is to be fired perfectly horizontally, what should the launching speed of the bomb be in order to hit the target? What is the duration it would take the bomb to hit the target? Find x(t) and y(t). Consider the initial location of the tank to be (0, 1 km)? Draw the trajectory of the bomb (x and y coordinates). Indicate clearly the value of x (horizontal displacement) when the bomb reaches the ground level. 5.     Draw the (?), ??(?), and ??(?) vertical above each other. Indicate key values on the graphs such as the start, the end, the maximum, the minimum and the x and y intercepts. PART 4 and 5 PLEASE.

EXERCISE HINTS: GETTING STARTED | I'M STUCK! Use the values from PRACTICE IT to help you work this exercise. Suppose the same two vehicles are both traveling eastward, the compact car leading the pickup truck. The driver of the compact car slams on the brakes suddenly, slowing the vehicle to 5.97 m/s. If the pickup truck traveling at 17.4 m/s crashes into the compact car, find the following. (a) the speed of the system right after the collision, assuming the two vehicles become entangled m/s (b) the change in velocity for both vehicles Av truck= m/s m/s Av car= (c) the change in kinetic energy of the system, from the instant before impact (when the compact car is traveling at 5.97 m/s) to the instant right after the collision ΔΚΕ =|

3) The ME Department just purchased a new mega-drone that weighs 220 lbs and can descend autonomously to land on its own. The drone company included the graph shown below for how much force is applied to the Thrust 'T'. If the operator allows the autonomous descent when the drone has an initial downward velocity of 2 ft/s, calculate the velocity of the drone after 3 seconds. T, Ibf V = 2ft/s 260 t, (s) 5:57 PM O 57°F Mostly sunny 3/6/2022 99+ P Type here to search Del PrtScn FB Home F9 End F10 PgUp PgDn F12 F11 F6 F7 F5 F4 Esc F2 F3 F1 Backspace & @ %23 2$ % 8 4. Y U Q W
