A block is released from rest at the top of the frictionless ramp shown in the figure. Mass 1 is 1.53 kg and it is released from a height of 1.01 m above the table. The block collides elastically with block 2, initially at rest. Mass 2 is 4.14 kg. How far from the base of the table does mass 1 eventually land if the table has a height of 2.54 m? (Take the initial direction of block one as positive.)

A small (35 g) block is sliding toward the right along a table when it hits a larger (90 grams) block that was at rest. After the collision, the large block slides 72 cm to the right before coming to a rest, while the small block bounces off the large block, sliding 1.5 m to the left before stopping. The somewhat rough table has a coefficient of kinetic friction of 0.42. What is the velocity of the small block just before it hits the larger block?

Sphere m1 with a mass of 1.0 kg collides with m2, which also has a mass of 1.0 kg, in an elastic collision.  If v2f= 15 m/s and θ2= 40°, determine v1i.  (Hint:  An elastic collision requires that the after-collision angle between the two velocities must be 90°.)

A 14.4-g wad of sticky clay is hurled horizontally at a 71-g wooden block initially at rest on a horizontal surface. The clay sticks to the block. After impact, the block slides d=11 m before coming to rest. The coefficient of friction between block and surface is µk=0.56. What is the normal force caused by the ground on the block/blob (again, consider them as one mass)?         2. What is the frictional force on the block/blob?        3. What is the work done by friction on the block/blob?

() THE FOLLOWING QUESTIONS ARE BASED ON THE INFORMATION GIVEN BELOW. Block m, of mass 15 kg moving with velocity v = 33 m/s on a frictionless plane collides block mg which is connected to block m3 by a long. massless spring with spring constant k = 7000 N/m: see the figure. Each of blocks mą and mg has a mass of 5 kg. Before the collision, blocks mą and mg are stationary and the spring is relaxed. m2 Frictionless - For parts A. B and Cassume that the collision of blocks m, and ma is completely inelastic. (Because the spring is relaxed before the collision. block mạ does not move at the instant of impact therefore (m, +m2) must move through a finite displacement before any force acts on mg and cause it to move) • For parts D and Eassume that the collision of blocks m, and m, is elastic. (Because the spring is relaxed before the collision. block my does not move at the instant of impact therefore mạ must move through a finite displacement before any force acts on mg and cause it to move)…

Male bighorn sheep (120 kg ) engage in head-butting contests to establish dominance. High-speed photography has shown that the impact speed is typically 6.0 m/s and that the collision, which brings both rams to a halt, lasts approximately 0.25 s . Suppose the collision force increases linearly with time until it reaches a maximum Fmax , then decreases linearly to zero at t = 0.25 s.  What is Fmax?

A man that weights 93kg sits on a 210 kg boat. After deciding he wants to stay at his current location with his boat motionless, he throws an anchor that weights 32 kg horizontally with the speed of 4.4m/s. Assume there is no resistance from the water. What is the velocity of the boat with man after the anchor was thrown? draw a picture round significant figures show work

In the figure, block 1 of mass m, slides from rest along a frictionless ramp from height h = 2.3 m and then collides with stationary block 2, which has mass m2 = 2m1. After the collision, block 2 slides into a region where the coefficient of kinetic friction Pk is 0.55 and comes to a stop in distance d within that region. What is the value of distance d if the collision is (a) elastic and (b) completely inelastic? - Frictionless 12 (a) Number i Unit (b) Number Unit

Treat the collision as elastic.  A moving billiard ball hits an identical (except for color) stationary ball.   After the collision, the orange ball always goes off in the positive x-direction.  The final speeds are v and V.  Calculate the angle θ that the green ball goes off in.  (θ should be positive.) V0 = the initial green body's speed = 6 m/s M = the mass of both balls = 6 kg φ = the incoming green ball's angle = 70o It's always a good idea to check your answer with the momentum-conservation and energy-conservation equations.

Dan is gliding on his skateboard at 2.56 m/sm/s . He suddenly jumps backward off the skateboard, kicking the skateboard forward at 6.22 m/sm/s (as measured by an observer on the ground). Dan's mass is 42.1 kgkg and the skateboard's mass is 5.99 kgkg . If the jump requires 0.122 ss to complete, what average force did Dan exert on the skateboard?
