A circus clown weighing 175 pounds is fired from a cannon at 50 degrees above the horizontal. The clown lands in a circular net that has a radius of 10 feet and located 9.1 feet above the ground. The closest edge of the net is 119 feet from the cannon. It takes 3.00 seconds for the clown to travel through the air and land in the exact center of the net. What was the initial velocity of the clown in ft/s? Please help!
A 4.95-kg ball, moving to the right at a velocity of +1.60 m/s on a frictionless table, Find the final velocities of the balls if the collision meet the following conditions
A bat emits a sound whose frequency is 91.20 kHz. The speed of sound in air at 20 degrees Celcius is 343m/s. However the air temperature is 38.8 degrees Celcius, so the speed of sound is not 343m/s. imagine that air behaves like an ideal gas, and ..
Mr. Gewanter, who's mass is 60.0 kg, is doing physics demonstration in the front of the classroom. a) How much gravitational force does he exert on 55-kg Martha in the front row, 1.50m away? b) How does this compare to what he exerts on 65-kg Lest..
Find the direction of the net electrical force electrons will exert on the proton. Enter your answer as an angle measured relative to the line connecting the proton and the right electron with counterclockwise being positive.
A car starts from rest at a stop sign. It accelerates at 4 for 6.4, coasts for 1.5, and then slows down at a rate of 3.5 for next stop sign. How far apart are the stop signs.
A 4.20kg steel ball strikes a wall with a speed of 7 m/s at an angle of 60° with the surface. It bounces off with the similar speed and angle. If the ball is in contact with the wall for 0.20 s, what is the average force exerted by the wall on bal..
The skis have a thrust of 190 . Sam's speed at the bottom is 35.0 . Illustrate what is the coefficient of kinetic friction of his skis on snow?
At t = 0 a grinding wheel has an angular velocity of 23.0 rad/s. It has a constant angular acceleration of 31.0 rad/s2 until a circuit breaker trips at t = 2.00 s. From then on, it turns by 432 rad as it coasts to a stop at constant angular accele..
An artificial satellite circles the Earth in a circular orbit at a location where the acceleration due to gravity is 4.50 m/s2
Use the value of the Sun's luminosity (3.90×10^26 watts, or 3.90×10^26 joules per second) to calculate what mass of hydrogen the Sun will convert into helium during its entire main-sequence lifetime of 1.2×10^10 years.
What is the current in amperes in a wire of radius. The parallel plates in a capacitor, with a plate area of 8.70 cm2 and an air-filled separation of 3.30 mm, are charged by a 8.90 V battery.
