A bomb is dropped from a plane which is flying with a constant horizontal velocity. Locate the bomb after 1 second in relation to the plane.
A block of mass m= 0.9 kg is attached to a spring of spring constant k= 500 N/m. the block is pulled to an initial position x = 5 cm to the right of the equilibrium point as shown below, and released from rest. Find the speed of the block as it passes through equilibrium if the coefficient of kinetic friction between the block and the surface μk = 0.35.
A grand father clock ticks each time the pendulum passes through the lowest point .if the pendulum is modeled as a simple pendulum .hiw long must it be for the ticks to occur once a second?
two possible angle to hit a target by a martyr shell fired with initial velocity of 98 metre per second are 15 degree and 75 degree calculate the range of projectile and the minimum time to required to hit the target
Assuming that the rest radius of earth is 6400 km and its orbital speed about the sun is 30 km/sec,
how much does earths diameter appear to be shortened to an observer on the sun, due to earth’s
orbital motion?
A metal block of mass M kg is attached to a spring of negligible mass and spring constant k as shown in Fig. 2, and is free to slide on a frictionless, horizontal surface. A clay ball of mass M/4 kg is fired at the block with velocity V m/s and sticks to it. The block is initially at rest and the spring is initially uncompressed. (a) (3 marks) What is the speed of the block and ball system immediately after the impact? (b) (4 marks) Write an equation for the position of the block as a function of time after the collision, assume that at t = 0 s, the instant of the impact, it is at X = 0 m, which is the unstretched point of the spring. Determine values for the amplitude, angular frequency in terms of the given quantities. Assume that X and V are positive to the left as shown. (c) (3 marks) Calculate the time period, maximum velocity and maximum acceleration of the motion of the spring block and ball system.
A jet flies 700km due north,then 300km due west,after which it moves 400km due north and 800 km due east.
Using vector notation,draw the movement
A steel ball A collides elastically with another steel ball and ball B is observed to move off at an angle theta with the initial direction of motion of A. The mass of B is five time that of A. Determine the direction in which A moves after collision and the speed of two balls
A train starts from rest and travel with uniform acceleration 0.5ms-2 for 20 secs. It then moved with the velocity it has acquired for another 30secs. The brakes are then applied and it decelerate to rest in further 10 secs. Draw the velocity time graph of the motion of the train.Using the graph, determine the retardation as the train is being brought to rest.
Determine the total distance covered by the train.
