Q-2: During a fireworks display, a shell is shot into the air with an initial speed of 70.0 m/s at an angle of 75.0° above the horizontal, as illustrated in the figure below. The fuse is timed to ignite the shell just as it reaches its highest point above the ground. (a) Calculate the height at…
Find the radius required for a synchronous (24 hr) satellite going in a circular orbit around the earth.
A block with mass m = 0.50 kg is forced against a horizontal spring of spring constant 100 N/m and negligible mass, compressing the spring distance of 0.20 m, as shown in Figure. When released, the block moves on a horizontal tabletop for 1.0 m before coming to rest. Find the coefficient of…
Considering the Compton scattering, derive the relation in which energy of scattered photon can be calculated from the energy of incident photon and the angle of the scattered photon.
A particle starts from the origin at t = 0 with an initial velocity of 5.1 m/s along the positive x axis.If the acceleration is (-3.1 i^ + 5.0 j^)m/s2, determine (a)the velocity and (b)position of the particle at the moment it reaches its maximum x coordinate. Answer needed in a) Vx, Vy …

The angular velocity of a flywheel obeys the equation ?z(t)=A+Bt^2, where t is in seconds and A and B are constants having numerical values 2.85 (for A) and 1.50 (for B ).
If you divide a force measured in newtons by a speed expressing meters per second in what unit all the answer be expressed
How it can be solved?
How fast must a meterstick be moving if its length is measured to shrink by 25% of its original length?
The potential energy U in Joule of a particle of mass is 4kg moving in the x-y plane is given by the formula U = 6x + 8y + 5. Here x and y are coordinates of the particle in meter. The particle is at (3,5) at t = 0 and v 0 = 0. i and jare the unit vectors across x and y…
A 3.67 g bullet is fired vertically into a 1.61 kg block of wood. The bullet gets stuck in the block and the impact lifts the block 0.071 m up. (That is, the block with the bullet stuck in it rises 0.071 m up above its initial position, and then falls back down.) Given g = 9.8 m/s2 What…
A hoop of mass M and radius R is rotating about an axle at the edge of the hoop. The hoop starts at its highest position and is given a very small push to start it rotating.
A sign uses energy at a rate of 65.0 W. a) How long, in seconds, will it take for the sign to use 255000 J of energy. b) What would 255000 J be in kilowatt-hours (kWh).
