An object moves along the x-axis according to the equation x = 2.55t2 - 2.00t + 3.00, where x is in meters and t is in seconds. If the train has an angular acceleration of -2.2 rads/s2 and is released with an angular speed of 17.0 rpm, what time is required for t... A transverse sinusoidal wave, traveling in the positive x direction along a string, has an amplitude of 20 \ cm. How far does the car travel in first 10 seconds? The maximum height reached by the rock is 5.0 m. Determine the rock's initial speed. The lau... A 124, kg balloon carrying a 22 , kg basket is descending with a constant downward velocity of 25.2, m/s , A 1.0, kg stone is thrown from the basket with an initial velocity of 11.7, m/s p... A football is thrown to a moving receiver. A) Find the total time of the fall. a. At the same time, a box starts from rest at the same altitude and slides down the same incline, with negligible friction.... A car travels from city A to city B at a constant speed of 60 km/h. When does the rocket reach its... (a) What linear speed must an earth satellite have to be in a circular orbit at an altitude of 197 km above earth's surface? The mass of a minibus with the driver is 1.50 \times 10^3 kg.Assume that the passengers have an average mass of 50.0 kg each.The driver is moving at a speed of 30.0 m/s when he notices that the tra... A 5000kg truck rear ends a 2500kg car. How many miles will the student travel if the trip lasts 8.73 hours? Solve the following equation for t. s = \dfrac{1}{10}gt^2. During this time, it travels a distance of 140 meters. How high will the ball go? With what velocity did it take off? The squirrel with nuts in its mouth headed back towards the nest for 35 meters when it... You are arguing over a cell phone while trailing an unmarked police car by 25.0 \ m; both your car and the police car are traveling at 120 \ km/h. 22\ \mathrm{m/s} c. 17\ \mathrm{m/s} d. Can not be determined. In the design of a rapid transit system, it is necessary to balance the average speed of a train against the distance between station stops. A box moves down a conveyor belt the is angled at 15^{\circ}, at a rate of 6 m/s. Aiden hits a volleyball upward with an initial velocity of 12 m/s. CBSE 2021 Board Exam: Case-Study, Assertion & Reason Based Questions, MCQs in English Subject & More Application Based Questions - Check Important Changes In Paper Pattern & Exam Dates Updates! b. a. If the ground is level, what is the maximum height reached... Use to position function s(t) = -4.9t^2 + vt + s for free-falling objects to estimate the height of a building, a stone is dropped from the top of the building into a pool of water at ground level. Find the distance... A new SpaceX rocket is being tested and launches from the ground. The sensor sends out an ultrasound pulse at t = 0.0 ms and registers the echoed return of that same pulse at t = 18.6 ms. How far away from... A particle starts at the point (5, 0) at t = 0 and moves along the x-axis in such a way that at time t >0 the velocity is given by v(t)=t/(1+t^2). A bicycle racer sprints near the end of a race to clinch a victory. If a ball is thrown into the air with a velocity of 33 ft/s, its height (in feet) after t seconds is given by y = 33t -16t^2. If this pitch were thrown horizontally, the ball would fall 0.809\ \mathrm{m} (2.65\ \mathrm{ft}) by the time i...
