A particle (m=5 kg) hits another identical particle. If v^0= 10m/s= initial speed. What are both particles final speeds if: A) They stick together? B) The collisio is elastic? C) The incoming particle bounces backwards at vf=1o m/s? (vxf=-10 m/s)
One particle of mass m1 = 1.00 kg with an initial velocity of 5.40 m/s i collides with a second particle of mass m2 = 2.00 kg that is initially at rest. After the collision mı goes off with a final speed of 4.20 m/s in a direction 32.0° above i. V 5.4 ms (a) Find the final velocity (in terms of magnitude AND direction) of m2. agnitude AND direction) of m. Vi = 4.2 m/s (HINT: Find the direction...
In a particle accelerator, a proton has mass 1.67 ✕ 10−27 kg and an initial speed of 4.00 ✕ 105 m/s. It moves in a straight line, and its speed increases to 7.00 ✕ 105 m/s in a distance of 35.0 cm. Assume that the acceleration is constant. Find the magnitude of the force (in N) exerted on the proton.
Two forces F1 = (-6i - 4j) N and F2 = (-3i + 7j) N act on a particle of mass 2.00 kg that is initially at rest at coordinates (-2.00 m, 4.00 m). What are the coordinates of the particle at time t = 10 s?
A m= 5.0 kg block slides on a flat, smooth track with an
initial speed of vi= 6 m/s. The block slides down a rough incline
that has a vertical height of h = 4 m onto another flat, smooth
track. The block’s final speed is vf= 10 m/s. How much energy is
lost to friction on the block as it slid down the incline?
