If the mass of the hanging-mass is increased and the mass of the cart remains the same, how would the steepness of the position versus t2 be affected? The best-fit line would decrease in steepness.The best-fit line would increase in steepness. Impossible to determine because the net force is not a part of the position vs t2 graph.There would be no change in steepness.
1. You are setting up for a pool party that has a 2.5 m high slide that launches swimmers into the pool. To make it more exciting, you decide to string a steamer across the pool so that the swimmers just clear it at their maximum height after leaving the slide. The end of the slide is 0.75 m above the ground and is directed 20° above the horizontal. By watching people use the slide, you know the horizontal distance to place the streamer, so you only need to determine the maximum height. You are also curious how fast the swimmers are going when they enter the pool. In your estimates, you can assume that the swimmer starts at rest at the top of the slide and ignore friction on the slide and air resistance. 2.5 m 0.75 m streamer If the angle of the slide were different (say 15°) would either the maximum height or the speed when entering the water be different? Note: Use conservation of energy to answer these questions.
1. The small rocket engines used in model rockets are rated by the impulse they exert on the rocket. The graph below shows the force exerted by an engine during the 1.0 second from when it is ignited until when the fuel is completely bumed. a) What is the impulse of this rocket engine? F(N) 0.2 0.4 0.6 0.8 1.0 b) One of these engines is put horizontally on a frictionless cart of mass 780 g so that it will accelerate the cart. How fast will the cart be going after the engine has burned all of its fuel? The mass of the engine itself is small enough that we can ignore it.
The initial cost of a pickup truck is $10,048 and will have a salvage value of $4,400 after five years. Maintenance is estimated to be a uniform gradient amount of $132 per year, with zero dollar for first year maintenance. The operation cost is estimated to be $0.26 per mile for 280 miles per month. If the interest rate is 12%, what is the annual equivalent cost (AEC) for the truck? Enter your answer as follow: 123456
A Water Balloon Battle. You are launching water balloons at a rival team using a large slingshot. The other team is set up on the opposite side of a flat-topped building that is 30.0 ft tall and 50.0 ft wide. Your reconnaissance team has reported that the opposition is set up 10.0 m from the wall of the building. Your balloon launcher is calibrated for launch speeds that can reach as high as 90 mph at angles between 0 and 85.0° from the horizontal. Since a direct shot is not possible (the opposing team is on the opposite side of the building), you plan to splash the other team by making a balloon explode on the ground near them. If your launcher is located 55.0 m from the building (opposite side as the opposing team), what should your launch velocity be ((a) magnitude and (b) direction) to land a balloon 5.0 meters beyond the opposing team with maximum impact (i.e. maximum vertical speed)?

2 Your friend is planning to ride his bike up a ramp and land on the roof of a building as shown below. The building is 6.00 m high and 8.00 m away from the ramp. The ramp is 3.00 m wide and 4.00 m tall. 4.00 m 1 ← 3.00 m 6.00 m 8.00 m A. What is the minimum speed with which your friend needs to leave the ramp in order to land on the building? B. Another friend is going to use his motorized scooter for the same stunt. The maximum speed of the scooter is 15.0 m/s. How close to the building should you move the ramp so that your friend lands on the roof right at the front edge of the building?
A completely automated Tesla travels up a 3% incline at 30 mph on a road that has good, wet pavement. The car has a wheelbase of 120 inches and a center of gravity that is 55 inches behind the front axle and at a height of 20 inches. The braking efficiency is 88%. It notices a pothole 35 ft ahead of the car and comes to a complete stop. a) Calculate the percentages of braking force that should be allocated to the front and rear brakes to ensure that maximum braking forces are developed. b) Will the car hit the pothole if it has (i) no antilock brakes and (ii) antilock brakes (braking efficiency 100%)? Assume theoretical stopping distance and neglect aerodynamic resistance.
Ed, Edd and Eddy love to play on a seesaw. It consists of a 1-kg board with a length of 8 meters. One day, the other end broke down. They had to cut it by a meter and maintain the pin support in its original position. Then, they tried the seesaw altogether. Ed (m = 55kg) sat on one side about 3m from the pin while Edd (m = 40kg) and Eddy (m = 40kg) on the other side. If Edd was about 3m as well from the pin, calculate the following: The magnitude of the reaction force (N) exerted by the pin support on the board. Assume Eddy is in between Ed and Edd. (mass of board = 1kg) *no diagrams were provided

1. In general, what pattern do you notice between the force due to the gravity of the masses and the displacement of the spring? 2. What is the physical meaning of the slope? 3. Using the slope for each spring, what would be the force required to stretch the spring 0.10 m? 4. Using the slope for each spring, what would be the amount of stretch with a 500 g mass hanging on the spring? Ps: pls refer to the graph below
