Find the weight of the hanging mass when the spring, with spring constant 15.5 kN/m , has been stretched 15.1cm. The tension in rod BD is 4150 N . Recall that the pulley is massless.
The bullet remains in the block, and after the impact the block lands d = 2.2 m from the bottom of the table. Identify the initial speed of the bullet.
An object moves up and down y-axis with an acceleration given as a function of time t by the expression a = A sin ω t, where A and ω are constants. What is the period of this motion.
Determine the maximum load in terms of theta_min and other quanitites given in the problem introduction.
A highway curve with a radius of 555 m is banked properly for the car travelling 150 km/h. If a 1650 kg Porshe 928 S rounds the curve at 220 km/h, how much sideways force must the tires exert against the road if the car does not skid.
