A speedboat with a length of 10.2m and a mass of 237 kg is negotiaging a circular turn (radius = 32 m) around a buoy. During the turn, the engine causes a net tangential force of magnitude 506 N to be applied to the boat. The intial speed of the boat going into the turn is 4 m/sec. 1) What is the tangential acceleration of the boat, 2 sec into the turn? aT = 2) What is the tangential velocity...
A speedboat with a length of 10.2m and a mass of 217 kg is negotiaging a circular turn (radius = 34 m) around a buoy. During the turn, the engine causes a net tangential force of magnitude 526 N to be applied to the boat. The intial speed of the boat going into the turn is 4 m/sec. 1) What is the tangential acceleration of the boat, 2 sec into the turn? aT m/sec Submit 2) What is the tangential...
A train is rounding a circular curve whose radius is 1.89E+2 m. At one instant, the train has an angular acceleration of 1.21E-3 rad/s2 and an angular speed of 0.0544 rad/s. Find the magnitude of the total acceleration (centripetal plus tangential) of the train.
A speedboat starts from rest and accelerates at +2.01 m/s2? for 6.90 s. At the end of this time, the boat continues for an additional 5.80 s with an acceleration of +0.518 m/s2. Following this, the boat accelerates at-1.49 m/s2 for 8.15 s. (a) What is the velocity of the boat at t = 20.85 s? (b) Find the total displacement of the boat.
The Texas Motor Speedway is an oval racing track with curves of radius 229 m that are banked at an angle of 24.0°. The size of the track allows for race cars to achieve speeds in excess of 400 km/h. An unintended consequence of the banked curves and high speeds is that race car drivers experience excessive G forces, especially in the "vertical" direction (with respect to their body position), causing dizziness and loss of consciousness. (a) A daring driver,...
A race car rounds a curve at 59 m/s. The radius of the curve is 403 m, and the car's mass is 640 kg. (Assume the car's speed remains constant. Take the radially inward direction to be positive. Indicate the direction with the sign of your answer.) (a) What is the car's (centripetal) acceleration? (b) What is it in g's? (enter value to 3 decimal places) (c) What is the centripetal force acting on the car?
