- A 54.9-kg skater is standing at rest in front of a wall. By pushing against the wall she propels herself backward with a velocity of -1.93 m/s. Her hands are in contact with the wall for 1.09 s. Ignore friction and wind resistance. Find the average force she exerts on the wall (which has the same magnitude, but opposite direction, as the force that the wall applies to her). Note that this force has direction, which you should indicate with the sign of your answer. Number -9.72 UnitsWhile hauling a log in the back of a flatbed truck, a driver is pulled over by the state police. Although the log cannot roll sideways, the police claim that the log could have slid out the back of the truck when accelerating from rest. The driver claims that the truck could not possibly accelerate at the level needed to achieve such an effect. Regardless, the police write a ticket, and the driver's court date is approaching. The log has a mass of m = 934 kg; the truck has a mass of M = 8.90 × 10³ kg. According to the truck manufacturer, the truck can accelerate from 0 to 55 mph in 24.0 s, but this does not account for the additional mass of the log. Calculate the minimum coefficient of static friction μ needed to keep the log in the back of the truck. μs = Given this fact, select the most accurate statement. M According to the scientific literature, the coefficient of static friction between the log and the trailer bed should be roughly 0.840. The police officer is correct. The log…When serving a tennis ball, the player hits it when its velocity is zero (at the highest point of a vertical toss). The racket exerts a force of 510 N on the ball for 5.00 ms, giving it a final velocity of 47.0 m/s. Using these data, find the mass (in g) of the ball.
- A box of unknown mass is sliding with an initial speed vi = 4.90 m/s across a horizontal frictionless warehouse floor when it encounters a rough section of flooring. The coefficient of kinetic friction between the floor and the box is 0.625. How far does the box slide before stopping?A 6.3-kg toboggan is kicked on a frozen pond, such that it acquires a speed of 2.2 m/s to the right. The coefficient of friction between the pond and the toboggan is 0.18. Determine the distance that the toboggan slides before coming to rest. Answer: m (round to the nearest hundredth)A golf ball of mass 4.50x10^-2 kg is struck by a club. Contact lasts 2.00x10^-4 s, and the ball leaves the tee with a horizontal velocity of 50.0 m/s. Compute the average force the club exerts on the ball by finding its average acceleration.
