Determine the acceleration of a forklift of mass 1400 kilogram pushed by a force of 2100 Newton that is opposed by a frictional force of 425 Newton.
In Fig. 15-53, three 18000 kg ore cars are held at rest on amine railway using a cable that is parallel to the rails, which areinclined at angle θ = 34°. The cable stretches 21 cm justbefore the coupling between the two lower cars breaks, detachin..
If the intensity of the electromagnetic radiation produced by the Sun is about 1.4 kW/m2 near the Earth, what size would a sail have to be to accelerate a spaceship with a mass of 11.9 metric tons at 1.39 m/s2
A 0.255 kg puck, initially at rest on a frictionless horizontal surface, is struck by a 0.200 kg puck that is initially moving along the x axis with a velocity of 2.06 m/s. After the collision, the 0.200 kg puck has the speed of 1.02 m/s at an ang..
A large boulder rests on a cliff 500 m above a small village in such a position that, if it should slide off, What is the final impact velocity of the boulder
The driver of one car sounds a 365 Hz frequency horn and the driver of the other car hears a frequency of 392 Hz, Determine the speed of both cars
Two Stars of equal mass revolve in a circular orbit about a center of mass midway between them. Find the mass of each star
A small block with mass 0.200 kg is attached to a string passing through a hole in a frictionless, horizontal surface. What is the radius of the circle when the string breaks
Your projectile launching system is partially jammed. It can only launch objects with an initial vertical velocity of 42.0 m/s, though the horizontal component of the velocity can vary.
