A 960 kg car is pulling a 310 kg trailer. Together the car and trailer move forward with an acceleration of 2.00 m/s2. Ignore any frictional force of air drag on the car and all frictional forces on the trailer.
(a) Determine the net force on the car.
(b) Determine the net force on the trailer.
(c) Determine the force exerted by the trailer on the car.
(d) Determine the resultant force exerted by the car on the road. (Assume that the forward direction is along the +x-direction.)
An attacker at the base of a castle wall 3.75 m high throws a rock straight up with speed 8.50 m/s from a height of 1.60 m above the ground. what is the rock speed at the top
For what initial speed will a golf ball that leaves the ground at an angle of 60 degrees pass through a hole 20 meters above the ground in a building that is 60 meters away?
A projectile is fired with an inital speed ofvi=20m/s at an angle θ=30o with the horizontal. Find the horizontal component of the projectiles's velocity at the instant jus before it hits the ground. Find the vertical component of the projectiles's ve..
One of James BOnd's adversaries is standing on a frozen lake; there is no friction between his feet and the ice. what is the magnitude of his horizontal recoil velocity
a solid sphere rolls up an incline plane. what is the direction of the frictional force at the point of contact. next
What is sweep time of a scan with a sweep rate of 60Hz? Is the true resistance greater or smaller than the gauged resistance? Is the time base affected by changing the horizontal and vertical gains?
A horizontal plank of mass m and length L is pivoted at one end. The plank's other end is supported by a spring of force constant k. Find the angular frequency (omega) of simple harmonic motion
vector a which is directed along an x axis is to be added to vector which has a magnitude of 7.0 m. the sum is a third
An 83.6-mH inductor and a 6.22-µF capacitor are connected in series with agenerator whose frequency is 355 Hz. Therms voltage across the capacitor is 2.36V. Determine the rms voltage across the inductor.
Power transmission lines often use a form of electric current called alternating current, but in many regions, such as the Province of Quebec, high-voltage direct-current lines are used instead. What is the power loss due to resistance in the line
