Georgia, standing on the back of the pick-up truck, wants to throw her last piece of balut to her mortal enemy, Emma. before the truck started moving, the two women are separated by a distance of 2 m. For two seconds, the truck uniformly accelerated until it reached a velocity of 4 m/s which it then maintained. With hatred, Georgia throws the last piece of balut with a velocity of 12.5 m/s at an angle of 40° from horizontal, measured relative to the truck. If she makes the throw 2.8 seconds after the truck started moving, will she be able to hit Emma? Note that Emma is at rest due to exhaustion from their earlier fight and she cannot dodge the balut. Set your origin at point A. Neglect air resistance.
You are investigating an accident that occurred early on a foggy morning in Oxfordshire. A 2015 Prius Hatchback traveling due north collided in a highway intersection with a 2012 Nissan Pathfinder that was traveling due east. After the collision, the wreckage of the two vehicles was locked together and skidded across the level ground until it struck a tree. You measure that the tree is 11 m from the point of impact. The line from the point of impact to the tree is in a direction 39° north of east. From experience, you estimate that the coefficient of kinetic friction between the ground and the wreckage is 0.45. Shortly before the collision, a police officer with a laser speed gun measured the speed of the Prius to be 80 km/h and, according to a witness, the Prius driver made no attempt to slow down. Four people with a total mass of 230 kg were in the Nissan. The only person in the Prius was the 80 kg driver. The Nissan with its passengers had a mass of 2362 kg, and the Prius with its…
During a head on collision, the passengers in the front seat of a car accelerate from 13.3m/s to rest in 0.10s. The driver of the car held out their arm to stop their 25kg child from smashing into the dashboard. What force in pounds (1N = 0.225lbs) is needed to keep the child from moving?
A child with mass of 16.5 kg stands on the edge of a park bench and leaps into the air. Her initial speed is 2.4 m/s directed at an angle of 30 degrees above the horizontal. After 0.28 seconds what is the horizontal component of her velocity in m/s?
The block of mass m = 2 kg is released from the rest on the incline. If 0 = 15°, what is the velocity of the block 2 seconds after release? Ms = 0.3, k = 0.20 1.288 m/s 3.084 m/s 2.511 m/s m 0 Ө
You go watch your friend as she runs at a cross country meet. The first time she passes you, your friend runs by going due north at a speed of 4.40 m/s. You move to a different place on the course and twelve minutes after you saw her the first time, your friend runs past you again. This time she is traveling at a speed of 3.80 m/s in the direction 30.0° W of S. What is the direction of her average acceleration between those same two times?

A 5.0-kilogram grenade lying motionless on the ground explodes into three pieces. (It's not a very sophisticated grenade.) A 2.0-kilogram piece flies off at 18 meters per second and 110 degrees. A 1.7-kilogram piece flies off at 31 meters per second and 270 degrees. What is the velocity of the third piece? Include units in your answers.
A 238U nucleus is moving in the x direction at 5.0×105 m/s when it decays into an alpha particle (4He) and a 234Th nucleus. If the alpha particle moves off at 22 degrees above the x axis with a speed of 1.1×107 m/s, a) What is the speed of the thorium nucleus and b) What is the direction of the motion of the thorium nucleus ( degrees clockwise from the x axis)?
A golf ball is hit from the ground (elevation is zero) and takes off with a launch speed of 55 m/s and a launch angle of 25 degrees. The acceleration due to gravity g = 9.81 m/s2 downward (negative y direction). The wind resistance is proportional to velocity and is defined by constant k = 0.014 N / (m/s). The mass of the golf ball m = 46 grams. 1) Determine the horizontal x1(t) and vertical y1(t) positions as a function of time ignoring air / wind resistance in both the x and y directions. 2) Determine the horizontal x2(t) and vertical y2(t) positions as a function of time including air / wind resistance in both the x and y directions. 3) For the case ignoring wind / air resistance, calculate how long the ball is in the air (in seconds) and how far away the ball lands from where it was hit (in meters).
An engineering student throws a calculator straight up to a COVID-quarantined friend, who is leaning out a window 5.12 m above. The friend catches the calculator 1.43 s later and immediately sanitizes it and her hands. Taking up as the positive direction, find the calculator's velocity v just before it was caught.
