- If the contact surface between the 30-kg block and the ground is smooth, determine the power of force F if block reaches speed of 3.2 m/s when t = 4 s. Initially, the block is at rest.arrow_forwardThe spring is placed between the wall and the 10-kg block. If the block is subjected to aforce of F = 500 N, determine its velocity when s = 0.5 m. When s = 0, the block is at restand the spring is uncompressed. The contact surface is smooth.arrow_forwardThe car has a mass m0 and is used to tow the smooth chain having a total length l and a mass per unit of length m. If the chain is originally piled up, determine the tractive force F that must be supplied by the rear wheels ofthe car, necessary to maintain a constant speed v while the chain is being drawn out.arrow_forward
- 14-76. The 4-kg smooth collar has a speed of 3 m/ s when it is at s = 0. Determine the maximum distance s it travels before it stops momentarily. The spring has an unstretched length of l marrow_forwardThe 50-kg crate is hoisted up the 30o incline by the pulley system and motor M. If the crate starts from rest and by constant acceleration attains a speed of 6.4 m/s after traveling 18.1 m along the plane, determine the power in kW that must be supplied to the motor at this instant. Neglect friction along the plane. The motor has an efficiency ϵ = 0.78.arrow_forwardWhen the 5 kg block is 6 m from the wall, it is sliding at v1=14 m/s. If the coefficient of kinetic friction between the block and the horizontal plane is µk=0.3, determine the impulse of the wall on the block necessary to stop the block. Neglect the friction impulse action on the block during the collison.arrow_forward
- If the cord is subjected to a constant force of F = 300 N and the 15-kg smooth collar starts from rest at A, determine the velocity of the collar when it reaches point B. Neglect the size of the pulleyarrow_forwardA tugboat T having a mass of 19 Mg is tied to a barge B having a mass of 75 Mg. If the rope is "elastic" such that it has a stiffness of k=600kN/m, determine the maximum stretch in the rope during the initial towing. Originally both the tugboat and barge are moving in the same direction with speeds (vT)1= 15 km/h and (vB)1= 10 km/h, respectively. Neglect the resistance of the water.arrow_forwardThe 81-kg crate is subjected to the forces shown. If it is originally at rest, determine the distance it slides in order to attain a speed of v = 8 m/s. The coefficient of kinetic friction between the crate and the surface is uk = 0.27. Forces with respect to 45° and 30° are 611 N and 398 N, respectivelyarrow_forward
- The 1500-kg car has a velocity of 30 km/h up the 10-percent grade when the driver applies more power for 8 s to bring the car up to a speed of 60 km/h. Calculate the time average F of the total force tangent to the road exerted on the tires during the 8 s. Treat the car as a particle and neglect air resistance.arrow_forwardF14-1. The spring is placed between the wall and the 10-kg block. If the block is subjected to a force of F = 500 N, determine its velocity when s = 0.5 m. When s = 0, the block is at rest and the spring is uncompressed. The contact surface is smooth. S00N Prob.
