A bullet with a mass of 0.01 kg is tired horizontally into a block of wood hanging on a string. The bullet sticks in the wood and causes it to swing upward to a height of 0.1 m. If the mass of the wood block is 2 kg, what was the initial speed of the bullet?
In Figure OQ5.2, a locomotive has broken through the wall of a train station. During the collision, what can be said about the force exerted by the locomotive on the wall? (a) The force exerted by the locomotive on the wall was larger than the force the wall could exert on the locomotive. (b) The force exerted by the locomotive on the wall was the same in magnitude as the force exerted by the wall on the locomotive. (c) The force exerted by the locomotive on the wall was less than the force exerted by the wall on the locomotive. (d) The wall cannot be said to exert a force; after all, it broke. Figure OQ5.2
In a laboratory model of cars skidding to a stop, data are measured for four trials using two blocks. The blocks have identical masses but different coefficients of kinetic friction with a table: k = 0.2 and 0.8. Each block is launched with speed vi = 1 m/s and slides across the level table as the block comes to rest. This process represents the first two trials. For the next two trials, the procedure is repeated but the blocks are launched with speed vi = 2 m/s. Rank the four trials (a) through (d) according to the stopping distance from largest to smallest. If the stopping distance is the same in two cases, give them equal rank. (a) vi = 1 m/s, = 0.2 (b) vi = 1 m/s, k = 0.8 (c) vi = 2 m/s, = 0.2 (d) vi =2 m/s, k = 0.8
A boy coasts down a hill on a sled, reaching a level surface at the bottom with a speed of 7.00 m/s. If the coefficient of friction between the sleds runners and the snow is 0.050 0 and the boy and sled together weigh 600. N, how far does the sled travel on the level surface before coming to rest?
Professional Application (a) Calculate the maximum rate at which a rocket can expel gases if its acceleration cannot exceed seven times that of gravity. The mass of the rocket just as it runs out of fuel is 75,000-kg, and its exhaust velocity is 2.40103 m/s. Assume that the acceleration of gravity is the same as on Earth's surface (9.80 m/s2). (b) Why might it be necessary to limit the acceleration of a rocket?
As part of a safety investigation, two 1400 kg cars traveling at 20 m/s are crashed into different barriers. Find the average forces exerted on (a) the car that hits a line of water barrels and takes 1.5 s to stop, and (b) the car that hits a concrete barrier and takes 0.10 s to stop.
Suppose an unpowered go-cart (with a child rider) traveling at an initial speed of 5 m/s. Coast on a level road for about 50 m before coming to rest. If the cart and rider have a mass of 40 kg, about what force would you have to apply to keep the cart moving at a constant speed? Assume that the friction forces acting on the cart are approximately independent of its speed. (Hint: Use the “momentum requirement” to compute the magnitude of the total friction per drag force acting on the cart, then link this force to the force you must apply.)
Physics A catcher in a baseball game stops a pitched ball originally moving at 49.0 m/s49.0 m/s in the positive direction at the moment it first comes in contact with the catcher’s glove.

While playing basketball in PE class, a student lost her balance after making a lay-up and collided with the padded wall behind the basket. Her 37 kg body decelerated from 6.6 m/s to 0 m/s in 0.21 seconds. a) Determine the magnitude of the average force in Newtons acting on the student's body during the impact with the padded wall. If the student instead hit the concrete wall moving at the same speed, her momentum would have been reduced to zero in 0.07 seconds. Determine what the magnitude of the average force in Newtons acting on her body would have been for such an abrupt and dangerous collision?
After falling from rest from a height of 30-m, a 0.50-kg ball rebounds upward, reaching a maximum height of 20-m. If the contact between the ball and the ground lasted 20 milliseconds, what average force was exerted on the ball by the ground? (Hint: consider the change in velocity that has occurred between the interval just before and just after hitting the ground). Answer: 1.1 x 10^3 N
Based on a grade 11 physics student, answer the following question: In the Loblaws parking lot, the cart attendants decide to have some fun during a winter morning. The two attendants, Otis (72 kg) and Sito (82 kg), exert a minimum horizontal force of 29 N [F] to get their 153 kg carts to begin moving. After the carts have travelled for 11m, Otis and Sito jump on and the carts have a friction of 33 N. a. Draw a free body diagram of the carts at rest, and another one after they have travelled 11m, showing all forces and with values.
In a shuffleboard game, the puck slides a total of 12 m before coming to rest. If the coefficient of kinetic friction between the puck and board is 0.10, what was the initial speed of the puck? Can you point to some formula, why you chose that formula, then explain the factors in the physics dynamics. I don't quite understand.
