Q1. After a tornado, a 0.60 straw was found embedded 2.7 into the trunk of a tree. If the average force exerted on the straw by the tree was 85, what was the speed of the straw when it hit the tree?
Q2. A baseball is bunted down the third-base line leaving the bat from a height of 0.850m with an initial velocity of 4.00m/s at an angle of 37.87° above horizontal
a) what is the speed of the baseball just before hitting the ground? (Answer by using mechanical energy conservation)
b) What is ball's normal (centripetal) acceleration at the maximum height?
c) What is baseball's tangential acceleration at maximum height?
d) Reply b and c for the instant just before the ball hits the ground
e) what are the radiuses of the baseball path curvature at the greatest height and the point of grounding.
What is the amplitude of subsequent oscillations
Determine the simple harmonic motion of the spring what ac velocity is ball moving
After being accelerated to a speed of 1.84×105, the particle enters a uniform magnetic field of strength 1.00 and travels in a circle of radius 35.0. The results of this experiment allow one to find.
A block of mass 2.7 kg being released from rest on a 1m frictionless plane, inclined at an angle of 40 degree. The block sided down the inclined and struck second block mass of 3.7 kg. If the two blocks stick together, with what speed would they move..
What is the velocity of each ball after the elastic collision? What will be the highest height of each ball after the elastic collision .
A screen is placed 42.7 cm from a single slit that is illuminated with light of wavelength 677 nm. If the distance between the first and third minima in the diffraction pattern is 3.45 mm, what is the width of the slit.
A 18.0 kg block is dragged over a rough, horizontal surface by a constant force of 77.6 N acting at an angle of 35? above the horizontal. The block is displaced 10.8 m, and the coefficient of kinetic friction is 0.149.
What friction torque is necessary to reduce its angular speed from 90.0 {rm rpm} to 45.0 {rm rpm} in a time interval of 32.0 {rm s}.
A spring with spring constant 14 hangs from the ceiling. A ball is attached to the spring and allowed to come to rest. It is then pulled down 3.0 and released. The ball makes 17 oscillations in 16 seconds. What is it the mass of ball.
What is new angular speed of the merry-go-round
How to find out potential energy
A pet-store supply truck moves at 25m/s north along a highway. Inside, a dog moves at 1.85m/s at an angle of 35° east of north. What is the velocity of the dog relative to road.
