Phys201-1 Summer2020 <A HW (Part 1)Phys201 Problem 7.79 A block of mass m = 2.70 kg starts from the rest and slides down a 300 incline which is 3.60 m high. At the bottom, it strikes a block of mass M-7.50 kg which is at rest on a horizontal surface (Figure 1). (Assume a smooth transition at the bottom of the incline.) The collision is elastic, and friction can be ignored Determine the speed of the block with mass m2.70...
A block of mass m = 3.00 kg starts from the rest and slides down a 30.0∘ incline which is 3.60 m high. At the bottom, it strikes a block of mass M = 6.40 kg which is at rest on a horizontal surface (Figure 1). (Assume a smooth transition at the bottom of the incline.) The collision is elastic, and friction can be ignored. (A) Determine the speed of the block with mass m = 3.00 kg after the...

1. The block shown in (Figure 1) has mass m = 7.0 kg and lies on a fixed smooth frictionless plane tilted at an angle θ = 24.5 ∘ to the horizontal. a. Determine the acceleration of the block as it slides down the plane. Express your answer to three significant figures and include the appropriate units. b. If the block starts from rest 19.0 m up the plane from its base, what will be the block's speed when it...

A block of mass m 2.20 kg slides down an incline which is 3.60 m high. At the bottom, it strikes block mass M 7.00 kg which at rest on a horizontal surface, as 3.60 m shown (assume a smooth transition to the bottom of the incline). If the collision is elastic, and friction can of mass m 2.20 kg just before its strikes the block be ignored, determine (a) the speed of the block of mass M-7.00 kg. (b)...
A block of mass m = 2.26 kg slides down an α = 32.8 ° incline
which is h = 3.54 m high. At the bottom, it strikes a block of mass
M = 7.22 kg which is at rest on a horizontal surface, as seen in
figure below. (Assume a smooth transition at the bottom of the
incline.) If the collision is elastic, and friction can be ignored,
determine the speed of the smaller block after the collision.
