Q. A 5 kg fish is swimming at a speed of 1ms swallows a 1kg fish swimming toward it at 4 m/s. The speed of the larger fish after lunch is what?
Q. A 1.52 kg bottle of vintage wine is lying horizontally in the rack shown in the drawing. The two surfaces on which the bottle rests are 90.0° apart, and the right surface makes an angle of 45° with respect to the ground. Each surface exerts a force on the bottle that is perpendicular to the surface. What is the magnitude of each of these forces?
The potential at location A is 481 V. A positively charged particle is released there from rest and arrives at location B with a speed vB. The potential at location C is 878 V, and when released from rest from this spot, the particle arrives at B wit..
find out the magnitude of their acceleration. If the blocks move determine the magnitude of the tension in the string. If the blocks do not move determine the sum of magnitude of the forces of friction acting on the blocks. Show all the work.
Suppose a ping-pong ball and a bowling ball are rolling toward you with the same momentum, and you exert the same average force in stopping each of them.
A 258-kg log is pulled up a ramp by means of a rope that is parallel to the surface of the ramp. The ramp is inclined at 30.0° with respect to the horizontal. The coefficient of kinetic friction between the log and the ramp is 0.980, and the log has ..
Suppose that the mass of the dishwater is large as much as necessary so that its temperature does not change appreciably.
A plane flies from base camp to Lake A, 280 km away in the direction 20° north of east. After dropping off supplies it flies to Lake B that is 190 km at 30° west of north from Lake A. Graphically find out the distance and direction from Lake B to ..
Newton's universal constant of gravitation is G = 6.67 × 10-11 meters cubed (m3) per kilogram per second per second. The Sun's mass is M = 1.9891 x 10^30 kilograms. Earth's orbital period is P = 365.256366 days. Obtain the average radius of Earth's o..
An oil drop carries one excess electron and weighs 9.6 x10-15 N. What electric field strength is required to suspend the drop so it is motionless.
A barge of mass 5x 10^4 kg is pulled along the Erie Canal by two mules, walking along towpaths parallel to the canal on either side of it. The ropes harnessed to the mules make angles of 45° to the canal.
Speedy Sue, driving at 34.0m/s, enters a one-lane tunnel. She then observes a slow-moving van 175m ahead traveling with velocity 5.40 m/s. Sue applies her brakes but can accelerate only at 2.00 m/s2 since the road is wet. Will there be a collision..
