- A car has a mass of 1750 kg. If the driver applies the brakes while on a gravel road, the maximum friction force that the tires can provide without skidding is about 6500 N. If the car is moving at 22 m/s, what is the shortest distance in which the car can stop safely?arrow_forwardThe figure below is for a 6 kg box on a horizontal floor. Initially, you are pushing horizontally on the box and friction is opposing you. Then, you stop pushing the box. Use g = 10 m/s?. v(m/s) 8.0 6.0 4.0 2.0 1.0 2.0 3.0 t(s) Find the normal force acting on the box.arrow_forwardAkash and Beth are on skateboards. Beth and her skateboard have a combined mass of 62 kg. Akash and his skateboard have a combined mass of 150 kg. Beth pushes Akash to the left with a force of 120N. Assume no friction. What are the accelerations of Beth (+ skateboard) and Akash (+ skateboard)?arrow_forward
- A robot pushes a 20-kg giftbox on the horizontal surface as part of the moving job for the holiday season, the force is 27 N to the right as shown. The box does not move. The coefficients of friction between the floor and box are μs = 0.75 and μk = 0.40. What is the magnitude (absolute value) of the friction force on the box, in Newtons? Use g = 10 m/s2.arrow_forwardA brave but inadequate rugby player is being pushed backward by an opposing player who is exerting a force of 781 N, overcoming the force of friction between the losing player’s feet and the grass.The mass of the losing player plus equipment is 80.1 kg. The losing player is accelerating at 1.22 m/s² backward. What is the magnitude of the force of friction between the losing player’s feet and the grass?To solve this problem, draw a free-body diagram for the losing player. Then write the equation for the net force and acceleration in the horizontal direction, using variables for any unknowns. Finally, solvefor the force of friction, and calculate the magnitude of the force of friction on the losing player.arrow_forwardA cyclist is coasting at 18 m/s when she starts on a 450 m long slope that is 40 m high. The cyclist and her bicycle have a combined mass of 75 kg. A steady 15 N drag force due to air resistance acts on her as she coast all the way down to the bottom. a) Draw a useful picture depicting this situation. Clearly label all lengths and relevant vector quantities (velocity, force). b) How much enercy does the cyclist have at the top of the slope? c) How much work does the drag on the cyclist as she goes down the slope? Clearly indicate sign of work. d) What is the cyclist's speed at the bottom of the slope?arrow_forward
- A 3.45×103 kg train is stopped at a station. The train must go around a 149 m diameter corner right after it leaves the station. As the train leaves the station it provides a constant forward force of 1.67×103 N. What is the train's acceleration after 5.00 s?arrow_forwardAfter a day of testing race cars, you decide to take your own 1460.7 kg car onto the test track. While moving down the track at 10.7 m/s, you suddenly accelerate to 33.3 m/s in 12.4 s. What average net force have you applied to the car during that time? Answer in units of N.arrow_forwardAn object of mass m has these three forces acting on it . F1, F2, and F3 are shown in the figure. Assume the x-direction is to the right, and the y-direction is straight upwards. Let F1 = 7 N, F2 = 9 N, and F3 = 2 N.

- A flea jumps by exerting a force of 1.32 x 105 N straight down on the ground. A breeze blowing on the flea parallel to the ground exerts a force of 1.16 x 10-6 N on the flea. Find the direction and magnitude (in m/s²) of the acceleration of the flea if its mass is 6.0 x 107 kg. (Let us assume that Fwind points to the right. We will consider this to be the +x direction and vertical to be the +y direction.) magnitude 11.5 x Did you draw a free-body diagram, and identify the forces acting on the flea?
