A girl is skipping rocks across a lake. One of the rocks accidentally ricochets off a toy boat initially at rest in the water (see the picture). The 0.150-kg rock strikes the boat at a velocity of 13 m/s, 15° below due east, and ricochets off at a velocity of 11 m/s, 12° above due east. If the boat has a mass of 1.10 kg and assuming the water and air offer no resistance in the x-direction find the following: Note: The boat cannot move down due to the buoyancy force. (a) The velocity of the boat after the impact. (b) If the impact took 0.025s to occur, what was the average force between the rock and the block (magnitude and direction)? East 11 m/s 15° 13 m/s --East 12° (c) How much energy is lost during the collision?

A car of mass 1,907 kg collides with a wall. The initial speed of the car is 18.2 m/s. After collision, the car bounced in the opposite direction at a speed of 2.9 m/s. If the collision lasted for 172 ms, what was the average force in newtons exerted on the car by the wall? Express your answer in two decimal places with units of Newton.
A 3.45 kg black ball traveling 4 m/s has a head on collision with a white one at rest. Using the velocities shown, calculate the mass of the white ball, Ignore friction and air resistance. 0 m/s 4 m/s 1.4 m/s 5.7 m/s
Radical Albertan separatists are driving a tank at a constant speed of 10 m/s up a 45 degree mountain slope, in a vain attempt to invade British Columbia. Pursued by the Mounties, the tank fires a 10 kg watermelon, with muzzle velocity 25 m/s, back along its path. Ignore the distance from the muzzle to the slope. If the gun barrel is pointed 20 degrees above the horizontal as shown, how far is the melon from the tank (which keeps moving) when it finally strikes the slope below? Answer in m.
A 0.19kg baseball is pitched at 42m/s is struck by the bat with an average force of 700 N, which results in a velocity of 28m/s in the opposite direction from the original velocity. How long were the bat and ball in contact?
A 105-kg rugby player is initially running at 7.5 m/s in the positive direction, but collides head-on with a padded goalpost and experiences a backward force of 1.76 × 104 N for 5.55 × 10–2 s. Calculate the final velocity in the horizontal direction of the rugby player, in meters per second. vf =
A 38.0-kg boy, riding a 1.90-kg skateboard at a velocity of 5.60 m/s across a level sidewalk, jumps forward to leap over a wall. Just after leaving contact with the board, the boy's velocity relative to the sidewalk is 6.00 m/s, 9.60° above the horizontal. Ignore any friction between the skateboard and the sidewalk. What is the skateboard's velocity relative to the sidewalk at this instant? Be sure to include the correct algebraic sign with your answer.
One day a responsible young college student is driving his blue car (m = 931 kg) in an easterly direction and obeying the traffic laws with a leisurely velocity of v, = 12.12 m/s. Out of nowhere comes a crazed soccer mom driving her red minivan (M = 1261 kg) in a northerly direction at the insane velocity of V, = 21.81 m/s crashing straight into the innocent student. Their vehicles intertwine into a tangled pile of wreckage that eventually slides to a stop. We'll take the coefficient of friction to be: µk = 0.623. d%3? V2(wreckage) V2y=? v,(car) V=? V,(van) Not to scale The following summarizes the sequence of events occur: 1→ 2: The cars suffer an inelastic collision. • 2 → 3: The cars slide to a stop. Determine all the following: The x-component of the velocity of the wreckage immediately after the collision: V2x The y-component of the velocity of the wreckage immediately after the collision: V2y m/s The magnitude of the velocity of the wreckage immediately after the collision: V2 =…
As a car was passing through an intersection at 8.01 m/s [0.0°] it was hit broadside by a 1600 kg pickup truck running a red light at 8.38 m/s [90.0°]. Immediately after the 0.185 s collision, the velocity of the car was 5.68 m/s [62.4°], and the velocity of the truck was 6.12 m/s [48.78°].Based on the information in the above narrative, the mass of the car was a 1.20 ´ 103 kg. b 1.05 ´ 103 kg. c 9.50 ´ 103 kg. d 1.28 ´ 103 kg. please show all work, thank you
A freight train is being assembled in a switching yard, with two boxcars. Car 1 has a mass of m1= 61x10^3 kg and moves at a velocity of Vo1= +1 m/s. Car 2, with a mass of m2= 92x10^3 kg and a velocity 0f Vo2= +1 m/s, overtakes car ! and couples to it. Neglecting friction, find the common velocity (m/s) of the cars after they become coupled. Express in 3 decimal places.
