Q1. A man makes three consecutive displacements :(1) from O to A, (2)from A to B and (3) back to O. The magnitude of OA is 29.70 meters and of AB 47.24 m. If theta= 38.2°, find out the magnitude of the third displacement. Reply in units of m.
Q2. A whale comes to the surface to breathe and then dives at an angle of 20 degree below the horizontal.If the whale continues in a directly line for 196 m, how deep is it?
How far has it travelled horizontally?
What is the greatest angle of elevation
A 1.50 multiplied by 103kg car starts from rest and accelerates uniformly to 18.50m/s in 13s. Assume that air resistance remains constant at 400N during this time.
A number of people are riding in a hot-air balloon. The combined mass of the people and balloon is 281 kg. The balloon is motionless in the air, since the downward-acting weight of the people and balloon is balanced by an upward-acting 'buoyant' f..
A 151 kg rocket moving radially outward from Earth has a speed of 5.03 km/s when its engine shuts off 226 km above Earth's surface. (a) Assume negligible air drag; find the rocket's kinetic energy when the rocket is 535 km above Earth's surface. (b) ..
A gymnast of mass 56.0 {rm kg} hangs from a vertical rope attached to the ceiling. You can ignore the weight of the rope and assume that the rope does not stretch. Use the value 9.81 {rm m/s^2} for the acceleration of gravity.
What is the magnitude of an average acceleration of the ball
Light from a He-Ne laser (= 632.8) strikes a pair of slits at normal incidence, forming a double-slit interference pattern on a screen located 1.10 from the slits. The figure shows the interference pattern observed on the screen.
A skier, weighing 453 n, is skiing down a slope that has an incline of 29 degrees above the horizontal. Compute the acceleration of the skier (coefficient of kinetic friction between the skis and snow is 0.21)
A force vector points at an angle of 50.6° above the +x axis. It has a y component of +280 newtons. Calculate the magnitude of the force vector.
A 1.63 kg block of ice is sliding by you on a very slippery floor at m/s. As it goes by, you give it a kick perpendicular to its path. Your foot is in contact with ice block for 0.005 seconds. The block eventually slides at the angle of 24 degre..
A 430 microF capacitor is charged to 245 V. after that a wire is connected between the plates. How many joules of thermal energy are produced as capacitor discharges if all of the energy that was stored goes into heating the wire.
