- Two horizontal forces, and F2, are acting on a box, but only is shown in the drawing. F₂ can point either to the right or to the left. The box moves only along the x axis. There is no friction between the box and the surface. Suppose that F₁ = +4.6 N and the mass of the box is 3.6 kg. Find the magnitude and direction of F2 when the acceleration of the box is (a) +6.9 m/s², (b) -6.9 m/s², and (c) 0 m /s². (a) F₂ (b) F₁₂ (c) F₂ = II ◄► ◄► F₁ +xA car with a mass of 1.3x10° kg is skidding to a stop along a horizontal surface. The car decelerates from 33 m/s to rest in 3.9 seconds. Assuming negligible air resistance, determine the coefficient of friction between the car tires and the road surface.A hockey puck with mass 0.225 kg is at rest at the origin (x = 0) on the horizontal, frictionless surface of an ice rink. At time t = 0 a player applies a force of 9.50 N on the puck, parallel to the positive x- axis. She continues to apply this force until t = 0.850s. What are the position and speed of the puck at t = 0.850 s?
- A golf ball (m = 67.8 g) is hit by a clab that makes an angle of 25.1° with the horizontal. The ball lands 222 m away on a flat fairway. The acceleration of gravity is 9.8 m/s2. If the golf club and ball are in contact for 3.34 ms, what is the average force of impact? Neglect air resistance. Answer in units of N.Determine the force Q-> when the block moves with constant velocity. Express your answer in vector form.A hot air balloon begins to rise from rest. The lift on the balloon due to the buoyant force is 5000 N. In order to minimize the time until the passenger is reunited with their cell phone, what should the horizontal component of the passenger’s velocity be so that they land directly on their phone which is initially 3 m away in the horizontal direction?
- A small object is initially at rest at the top of a large solid sphere that is fixed on the ground. The small object then begins to slide along the surface of the large solid sphere, without friction. V₁ = 0 RI Part (a) Find the angle at which the small object loses contact with the large solid sphere. Part (b) Find the maximum horizontal distance traveled by the small object before it hits the ground. Take (xi, y₁) = (0,2R) as the coordinates for the top of the large solid sphere.A woman pushes a 10.0 kg box across a horizontal floor with a constant force of magnitude 40.0 N directed at an angle of -25° with respect to the positive x-axis. The box moves horizontally to the right. At the origin (x=0) the box has an initial speed of 4.00 m/s and the woman pushes it to a location ofx=3.00 m. what is the force of the woman? what is the force of gravity? what is the normal force of the floor?A person catches a ball with a mass of 145 g dropped from a height of 60.0 m above his glove. His hand stops the ball in 0.0100 s. What is the force exerted by his glove on the ball? Assume the ball slows down with constant acceleration.
- A commercial airplane is coming in for a landing. Just before it hits the runway it is moving at 76 m/s. The plane has a mass of 20,000 kg. The runway is 1.6km long and, obviously, the airplane needs to be stopped before it reaches the end of the runway. How large is the braking force the airplane needs to stop safely before the end of the runway?Two crates of fruit are released from the top of a ramp inclined at 30 degrees from the horizontal and 4.5 meter long. The two crates consist of an apple crate of mass 20 kg that is placed in front of a watermelon crate of mass 80 kg. The apple crate has a coefficient of friction of 0.20 while the watermelon crate has a coefficient of friction of 0.15. How long does it take the apple crate to reach the bottom of the incline if it needs to travel a distance of 4.5 meters?A car has a mass of 1520 kg. While traveling at 25 m/s, the driver applies the brakes to stop the car on a wet surface with a 0.40 coefficient of friction. How far does the car travel before stopping?
