A car makes a turn of radius 4 meters at a constant speed. The magnitude of the car's acceleration during the turn is 1.13 m/s2. How fast is the car moving during the turn in m/s?
A remote control car of mass 2,000 grams turns about a corner on a racetrack. While making the turn, it experiences a centripetal force of 0.9 N. If the toy car is traveling around the corner at a speed of 3.0 m/s, (a) what is the centripetal acceleration of the car? (b) What is the radius that the car turns about?
9. You are riding your bike and the brakes fail and the only way to stop before you end up over scenic drive is to use your leg and apply a torque to the tire to stop it in 2.0s. What torque is necessary to stop the bike if the tires radius is 0.33 with a mass of 1.5 kg and rotating at 98.7 rad/s? 10. They made some improvements to the new hover disk that exploded on you once...
3. A truck rounds a corner with radius of 50 meters with a speed of 30 m/'s. The truck hasa a. What is the centripetal force necessary to bring the truck around the corner at mass of 4000 kg. that speed? b. Assuming that the coefficient of friction between rubber and asphalt is o.8, can the truck safely make the turn at this speed? lf the truck can't make the comer, what is the maximum speed it can make the...
A student is riding their bike when they come across a turn in the form of a circular arc of radius R 3.0m as pictured in the diagram below and travel along this arc in the clockwise direction. At one point along this trajectory (the origin of the given coordinate system) it makes sense to define the Cartesian coordinate system shown where the x-axis is tangent to the trajectory and the y-axis is perpendicular to it. At this point the...
1) You are riding a bike at a speed of 4.3 m/s. You apply the rear brakes and come to a stop in 4 seconds. The moment of inertia of the rear bike wheel is 0.15 kg.m', and its radius is 0.33 m. If the rear wheel is rolling without slipping, what was the average torque exerted on it during the 4 seconds that you applied the brakes? (7 points)
100 Imagine you are riding your bike down St. Mary street at 7 ft/s, and you accelerate to make the light and cross Johnston St. If you are pedaling with an acceleration of 2.5 ft/s^2, how long will it take you to reach the light 100 ft away? Show your work. seconds
While riding on a bus traveling down the highway, you notice that it takes 2.1 min to travel from one roadside mile marker to the next one. A-What is your speed in mi/h? B-How long does it take the bus to travel the length of a football field?
Question 1 (10 marks) A 75 kg cyclist is riding a 9 kg road bike on flat ground at a constant Velocity of 8 m/s. The cyclist is using a power meter, which indicates that the cyclist's power output is 216 W. a) draw the FBD & KD for the cyclist (2 marks) b) use your FBD/KD to solve for the drag force that is acting on the cyclist for the conditions above (2 mark if the cyclist now wants...
5. A passenger of mass 85 kg is riding in an elevator while The scale only reads the normal force it exerts on the (Note that 1 b 0.453 kg 4.45 N) a) What standing on a platform scale. does the scale read in pounds (lb) when the elevator is not moving? elevator is moving upward with an acceleration of 3.5 m/s?? c) What does the scale read in pounds (b) when the elevator is same acceleration of 3.5 m/s??...
