An unstable particle of mass m decays in time t = 10^-10 s in its own rest frame. If its energy is E = 1000 mc^2 in the lab, how far (in meters) will it move before decaying? (Answer: 30 m)
A 45kg mass particle goes at 3m / s and collides with the upper edge of a uniform density disk with a mass of 175kg and a radius of 1.25m. The disk before collision was at rest. Without considering any type of friction, what will be the magnitude of the angular velocity of the disk with the particle attached to its edge just after the collision? 3 m/s R=1.25m Before After
10) The velocity (t) of a particle as a function of time is given by (h) - 023 m/s) (4.1 m/s2)+- (62 m/s3)2. What is the average acceleration of the particle between t = 10 s and t - 205? A) - 15 m/s2 B ) 15 m/s2 C) -13 m/s2 D) O m/s2 E) 13 m/s2 11) A car starts from rest and accelerates uniformly at 3.0 ms2 toward the north. A second car starts from rest 60 s...
6. The 200 g particle (Fig. 4) is released from point A at rest. The radus is 30 cm. The speed of the particle at point B is 1.5 m/s. (a) What is its kinetic energy at B? (b) How much energy is lost as a result of friction as the particle goes from A to B? (c) Is it possible to determine μ from these results in any simple manner? Explain. Figure 4
A speed of a rocket in space increases from 2*10^3m/s to 4*10^3m/s while its mass decrease by 60%. what is the exhaust speed of the gases
A particle, starting at rest, accelerates at 5 m/s2 for 10 s. It then decelerates to 30 m/s over a period of 10 s. The particle then moves at a constant speed for 20 s before decelerating to zero over a period of 5 s. 6. (12 points) A particle, starting at rest, accelerates at 5 m/s for 10 s. It then decelerates to 30 m/s over a 0 s. The particle tl of 5 s Plot the velocity and...
Problem 1 A boat heads north at 4 m/s for one hour, then turns and goes southeast (at 45° to the north) at 3 m/s for 45 minutes. a) How far has the boat gone? b) How far is it from it's starting location? Problem 2 Drawing a Cartesian coordinate system, plot an athlete running from point A (3,0) to point B (0,5) then to point C(-4,-2) and ending at point D (3,-1). Be clear in marking your coordinate system...
Additional problem(s); • The acceleration of a particle traveling along a straight path is shown in the graph below. The particle starts from rest. Sketch the velocity versus time and position versus time graphs. How far will the particle move during the 60-second time period shown? 6 5 4 3 2 1 a, m/s^2 0 -1 10 20 30 40 50 60 Time, s -2 -3 -4 -5
1) Starting from rest, a particle travels along the x axis with a constant acceleration of +3.0 m/s2. At a time 3.7 s following its start, it is at x = -102 m. At a time 6.6 s later it has a velocity of +30.9 m/s. Find its position at this later time. 2) A rock dropped from a cliff covers one-third of its total distance to the ground in the last second of its fall. Air resistance is negligible....
At a certain time a particle had a speed of 12 m/s in the positive x direction, and 3.2 s later its speed was 79 m/s in the opposite direction. What was the average acceleration of the particle during this 3.2 s interval?
