Consider a 672 N weight held by two cables. The left-hand cable had tension T2 and makes an angle of θ2 with the ceiling. The right-hand cable had tension 400 N and makes an angle of 35? with the ceiling. The right-hand cable makes an angle of 35? with the ceiling and has a tension of 400 N.
a) What is the tension T2 in the left-hand cable slanted at an angle of θ2 with respect to the wall?
Answer in units of N. b) What is the angle θ2 which the left-hand cable makes with respect to the ceiling?
If the current in the circuit is 0.15 A and the resistances are R1 = 100 ? and R2 = 260 ?, what is the emf of the battery.
An asteroid is discovered heading straight toward Earth at 15km/s. An international team manages to attach a giant rocket engine to the asteroid. The rocket fires for 10 min, after which the asteroid is moving at 29degree to its original path at a..

A bullet of mass m = 25 g is fired into a wooden block of mass M = 4.5 kg. The block is attached to a string of length 1.5 m. The bullet is embedded in the block, causing block to then swing.
Assume a rocketship in deep space moves with constant acceleration equal to 9.8 m/s2, which gives the illusion of normal gravity during the flight. Estimate the time required by a rocketship to attain the speed of light and the distance travelled t..
A car travelling at 37 {rm m/s} runs out of gas while travelling up a 7.0{rm ^ {circ}} slope. How far would it coast before starting to roll back down.
A boulder has 300J of potential energy sitting on the edge of cliff. What is the boulder's kinetic energy as it hits the ground.
What is the acceleration of two falling sky divers.
It collides with a 10,000 kg railway car resting at the bottom of the track with its brakes off. The two cars couple together and roll up the track to a height of h. find out h.
Take the initial direction of motion to be the positive direction. (Indicate the direction of the acceleration by the sign of your reply.)
If a person were to push hardly on a solid wall will the work be done? Also, why would it be exhausting to push hardly against this solid wall?
When the starter motor on a car is engaged, there is a 330A current in the wires between the battery and the motor. Suppose the wires are made of copper and have a total length of 1.5m .
