An object is thrown vertically upward and has a speed of 20.0 m/s when it reaches two thirds of its maximum height above the launch point. Determine,
a. Make a sketch of the motion, labeling all points and showing all the information you are given or know about it.
b. The velocity of the object at maximum height.
c. The maximum height reached by the object.
d. The initial velocity.
e. How long it takes for the object to reach its maximum height.
f. How long does it take to go down to the same height from which it was thrown.
g. The velocity of the object when it goes down to same height from which it was thrown.
One way to measure on another planet or moon by remote sensing is to measure how long it takes an object to fall a given distance. A lander vehicle on a distant planet records the fact that it takes 3.17 for a ball to fall freely 11.26.
A uniform plank of length 4.3 m and weight 201 N rests horizontally on two supports, with 1.1 m of the plank hanging over the right support (see the drawing). To what distance x could a person who weighs 449 N walk on the overhanging part of the p..
Find the change in momentum of a 1080 {rm kg} car that increases its speed from 5.0 {rm m/s} to 14.5 {rm m/s} in a time of 11 {rm s} while travelling in the same direction.
A copper block is removed from a 300°C oven and dropped into 1.00 kg of water at 20.0°C. The water quickly reaches 26.5°C and then remains at that temperature. What is the mass of the copper block?
The femur is a bone in the leg whose minimum cross-sectional area is about 4.5 x 10-4 m2. A compression force in excess of 7.7 x 104 N will fracture this bone. Bone has a compression Young's modulus of 9.4 x 10^9 N/m2
Three resistors are connected in series across a battery, What is the greatest voltage that the battery can have without one of the resistors burning up
A solid sphere and a solid cylinder with the same mass and radius roll down an inclined plane without slipping. Which one will reach the bottom of the incline first. Explain why. Assume friction is negligible for both.
An object placed on an equal-arm balance scale requires 12 kg to balance it. When object is placed on a spring scale, the spring scale reads 12 kg.
On your wedding day your lover gives you a gold ring of mass 3.98 g. 59 years later its mass is 3.73 g. On the average how many atoms were abrated from the ring during each second of your marriage? The atomic mass of gold is 177 u.
A potter's wheel is rotating at 3.2 rad/s in a counterclockwise direction when the potter turns it off and lets it slow to a stop. This takes 26 seconds. What is the average angular acceleration of the wheel during this time?
What is the kinetic energy of a ball of mass 16.1 kg at the apex (highest point) of its trajectory, if it is thrown with an initial speed of 45 mph and an initial angle of 42.8 o with respect to the horizontal?
Coherent light from a sodium-vapor lamp is passed through a filter that blocks everything except for light of single wavelength. It then falls on two slits separated by 0.410 . In resulting interference pattern on a screen 2.10 away, adjacent bri..
