Q1. A tiger leaps horizontally from a 5.90 m high rock with a speed of 4.10 m/s. How far from the base of the rock will she land?
Q2. A person walks 26 ° north of east for 3.4 km. How far due north and how far due east would she have to walk to arrive at same location?
Q3. A 260g piece of ice at 0°C is placed in 490g of water at 21°C. The system is in a container of negligible heat capacity and is insulated from its surroundings.
Find tension in the back muscle and the compressional force
Six mass pieces of 100g each are placed on a mass holder of 140g which is hung from a string. Analyse the tension in the string.
If the spring is stretched by 1.4 times the value in part A, and then released from rest, and the coefficient of kinetic friction between the box and the plank is 0.34, what is the magnitude of the initial acceleration of block as it starts moving..
When in deep space, the block accelerates at 4.2 m/s^2 even as a 120 N force is applied to it. The coefficient of static friction for a particular plane and this block is 0.31. What angle can this plane make with horizontal before the object starts t..
A projectile is launched from the top of a cliff above level ground. At launch the projectile is 35 meters above the base of the cliff and has the velocity of 50 meters per second at an angle 37° with horizontal. Air resistance is negligible.
A brick is thrown upward from the top of a building at an angle of 45° to the horizontal and with an initial speed of 10 m/s. If the brick is in flight for 2.8 s, how tall is the building.
What is momentum of the system immediately after the pack is thrown?
Compute coefficient of kinetic friction
A glider of mass 1.00 kg is allowed to oscillate under the influence of a spring of spring constant 25.6 N/m while on a frictionless, horizontal air track. At t = 0 s glider is released from rest at x = 5.00 cm. (At equilibrium, the glider is at x = ..
A helicopter is ascending vertically with a speed of 5.45m/s. At a height of 141m above the Earth, a package is dropped from a window. How much time does it take for package to reach the ground.
If you place a 0.0001-C charge halfway between the terminals of a common 9-v battery, 5 mm apart, what force will that charge experience.
