(a) What is the tangential acceleration of a bug on the rim of a 6.0 in. diameter disk if the disk moves from rest to an angular speed of 75 rev/min in 5.0 s? (b) When the disk is at its final speed, what is the tangential velocity of the bug? m/s (c) One second after the bug starts from...
Please do it correctly and do all parts as well. i'll definitely give you good feedback An automobile moves on a circular track of radius 0.95 km. It starts from rest from the point (x, y)(0.95 km, 0 km) and moves counterclockwise with a steady tangential acceleration such that it returns to the starting point with a speed of 30...
1. An 800 kg car travels around the edge of a circular track of radius 400 m. At one point, the car accelerates around the track, increasing its speed from 40 m/s to 60 m/s over the course of 5 s. At the instant that the car reaches 50 m/s find (a) its angular velocity (b) its radial acceleration, (c)...
(a) What is the tangential acceleration of a bug on the rim of a 12.0 in. diameter disk if the disk moves from rest to an angular speed of 76 rev/min in 3.0 s? m/s2 (b) When the disk is at its final speed, what is the tangential velocity of the bug? 0 m/s (c) One second after the bug...
A model train runs on a circular track with radius 1.5 m. Its tangential velocity is 2.0 m/s and it is accelerating with a tangential acceleration of 0.90 m/s2. What is the magnitude of the train’s overall acceleration? Find the angle between the overall acceleration and the centripetal acceleration.
An electric turntable 0.790 m in diameter is rotating about a fixed axis with an initial angular velocity of 0.280 rev/s and a constant angular acceleration of 0.881 rev/s2. a)What is the tangential speed of a point on the rim of the turntable at t = 0.192 s? Express your answer in meters per second. b)What is the magnitude of...
(a) What is the tangential acceleration of a bug on the rim of a 6.0 in, diameter disk if the disk moves from rest to an angular speed of 79 rev/min in 5.0 s? 425 Your response differs from the correct answer by more than 100%, m/ s (b) When the disk is at its final speed, what is the...
A hammer thrower accelerates the hammer (mass = 7.30 kg) from rest within four full turns (revolutions) and releases it at a speed of 27.7 m/s A.) Assuming a uniform rate of increase in angular velocity and a horizontal circular path of radius 1.30 m , calculate the angular acceleration. B.) Calculate the (linear) tangential acceleration. C.) Calculate the centripetal...
(a) What is the tangential acceleration of a bug on the rim of a 6.0 in diameter disk if the disk moves from rest to an angular speed of 79 rev/min in 5.0 s? 120 m/s? (b) When the disk is at its final speed, what is the tangential velocity of the bug? 630 m/s (c) One second after the...
Problems (6) and (7). Please be detailed with your answers. 6. The apparent weight of passengers (average mass of 75kg) on a roller coaster can decrease to zero as the car goes upside down in a loop-the-loop of 30.Om radius of curvature. Find the car's speed at the top of the loop if the passengers are to feel weightless. (12pts)...
