Block A with a weight of 100N (mA=10kg) moves to the right (vA=1 m/s) at the moment shown in the figure. Since the kinetic friction coefficient between the surface and block A is μk=0.2, find the speed of block B when it moves 2 meters its weight is 200N (mB=20kg)

What’s the correct answer for this please ?

An inclined plane of angle e = 20.0° has a spring of force constant k = 510 N/m fastened securely at the bottom so that the spring is parallel to the surface as shown in the figure below. A block of mass m = 2.61 kg is placed on the plane at a distance d = 0.297 m from the spring. From this position, the block is projected downward toward the spring with speed v = 0.750 m/s. By what distance is the spring compressed when the block momentarily comes to rest?

A block of mass m slides on a horizontal rough surface head on into a spring of spring constant k = 730 N/m, as shown in Figure. When the block is x = 0.8 meter away from the spring, it has a velocity v = 4.33 m/s. When the block stops, it has compressed the spring by 6.5 cm. The coefficient of kinetic friction between the block and the surface is 0.1. What is the block's mass m (in kg)? Provide your answer with 2 decimal places. Take g = 9.81 m/s2 V

Block A (m = 5 kg), seen in the figure, sits on a smooth surface and is attached by a slender rod to a ball-and-socket joint at B. If the moment and force shown are simultaneously applied to the block, what will the speed of the block be after 4 seconds (starting from rest)?

Two objects m1 = 5.15 kg and m2 = 2.95 kg)are connected by a light string passing over a light, frictionless pulley as in the figure below. The 5.15-kg object is released from rest at a point h = 4.00 m above the table. (a) Determine the speed of each object when the two pass each other. m/s(b) Determine the speed of each object at the moment the 5.15-kg object hits the table. m/s(c) How much higher does the 2.95-kg object travel after the 5.15-kg object hits the table? m
