Most geologists believe that the dinosaurs became extinct 65 million years ago when a large comet or asteroid struck the earth, throwing up so much dust that the sun was blocked out for a period of many months. Suppose an asteroid with a diameter of 2.0 km and a mass of 1.0 × 1013 kg hits the earth with an impact speed of 4.0 x 104 m/s. a. What is the earth's recoil speed after such a collision?
A 1.00×104 kg railroad car is rolling at 3.00 m/sm/s when a 6000 kg load of gravel is suddenly dropped in. What is the car's speed just after the gravel is loaded? Express your answer with the appropriate units(m/s).
Holding a slingshot at arm's length, he pulls the light elastic band back to his chin and releases it to launch a stone horizontally with a speed of 200 cm/s. Using the same procedure, a bean is thrown with a speed of 600 cm/s. What is the ratio of the mass of the bean to the mass of the stone? a. 1/3 b. 3 c. 9 d. 1/9 e. 1
Hi I am in physics I, and they have the problem: In a baseball game, the 145g ball reaches the batter with a speed of 15.0m/s. The batter hits the ball with a force as shown in exact oppositie direction. The peak force (F max) is 1500N. Find the ball speed right after the hit. It was solved like: J= mvf - mvi area=1/2*b8h J= area = 1500(6)/2 + 1500(2)/2 J=6000 J=6.0 N*s 6.0 N*s = (0.1 +5kg)vf - (0.145kg)(-15) solve for vf vf=26.38 I really don't understand where 0.1 came from. If you can just break down i bit how this is solve that would be great. Thanks!
A 0.10 kg bullet moving 250 m/s hits a 5.0 kg block of wood at rest. If the bullet becomes embedded in the wood (and if the block of wood is free to move), what is the speed of the system immediately after the impact? What percent of the kinetic energy is lost due to the impact?
The drawing shows a top view of a frictionless horizontal surface, where there are two springs with particles of mass m1 and m2 attached to them. Each spring has a spring constant of 250 N/m. The particles are pulled to the right and then released from the positions shown in the drawing. How much time passes before the particles are side by side for the first time at x = 0 m if (a) m1 = m2 = 6.0 kg and (b) m1 = 6.0 kg and m2 = 54 kg?
A 160 g baseball is thrown with a speed of 20 m/s. It is hit straight back toward the pitcher at a speed of 40 m/s. What is the maximum force that the bat exerts on the ball if the impulsive force registers at 0.60 milliseconds?
Three runaway train cars are moving on a frictionless, horizontal track in a railroad yard as shown in Figure P11.73. The first car, with mass m1 = 1.50 103 kg, is moving to the right with speed v1 = 10.0 m /s; the second car, with mass m2 = 2.50 103 kg, is moving to the left with speed v2 = 5.00 m/s, and the third car, with mass m3 = 1.20 103 kg, is moving to the left with speed v3 = 8.00 m /s. The three railroad cars collide at the same instant and couple, forming a train of three cars. a. What is the final velocity of the train cars immediately after the collision? b. Would the answer to part (a) change if the three cars did not collide at the same instant? Explain. FIGURE P11.73
Two objects are connected by a light string passing over a light, frictionless pulley as shown in Figure P7.7. The object of mass m1 = 5.00 kg is released from rest at a height h = 4.00 m above the table. Using the isolated system model, (a) determine the speed of the object of mass m2 = 3.00 kg just as the 5.00-kg object hits the table and (b) find the maximum height above the table to which the 3.00-kg object rises.
Two gliders are set in motion on a horizontal air track. A spring of force constant k is attached to the back end of the second glider. As shown in Figure P8.48, the first glider, of mass m1, moves to the right with speed v1, and the second glider, of mass m2, moves more slowly to the right with speed v2. When m1 collides with the spring attached to m2, the spring compresses by a distance xmax, and the gliders then move apart again. In terms of v1, v2, m1, m2, and k, find (a) the speed rat maximum compression, (b) the maximum compression xmax, and (c) the velocity of each glider after m1 has lost contact with the spring.
You hold a slingshot at arms length, pull the light elastic band back to your chin, and release it to launch a pebble horizontally with speed 200 cm/s. With the same procedure, you fire a bean with speed 600 cm/s. What is the ratio of the mass of the bean to the mass of the pebble? (a) 19 (b) 13 (c) 1 (d) 3 (e) 9
The coefficient of friction between the block of mass ml = 3.00 kg and the surface in Figure P7.22 is k = 0.400. The system starts from rest. What is the speed of the ball of mass, m2 = 5.00 kg when it has fallen a distance h = 1.50 m? Figure P7.22
