Coasting along at 7.00 m/s, a 60.0 kg bicyclist on a 6.70 kg bicycle encounters a small hill. If the speed of the bicyclist is 6.00 m/s at the top of the hill, find the work done by the net force on the bicyclist and her bike? (answer in J if possible thank you)
The average speed of a nitrogen molecule in air is about 6.70 ✕ 102 m/s, and its mass is about 4.68 ✕ 10-26 kg. (a) If it takes 2.90 ✕ 10-13 s for a nitrogen molecule to hit a wall and rebound with the same speed but moving in an opposite direction (assumed to be the negative direction), what is the average acceleration of the molecule during this time interval? m/s2 (b) What average force does the molecule exert on...
how to convert kg(m^2/s^2) to slug(ft^2/s^2)?
a cannon with velocity 300 m/s at angel 45,whats the range and height?
A force \(\vec{F}_{1}\) of magnitude 6.70 units acts on an object at the origin in a direction \(\theta=48.0^{\circ}\) above the positive x-axis. (See the figure below.) A second force \(\vec{F}_{2}\) of magnitude 5.00 units acts on the object in the direction of the positive y-axis. Find graphically the magnitude and direction of the resultant force \(\vec{F}_{1}+\vec{F}_{2}\)

Given: m-2 ft, n 4 ft, the angle θ of the incline is 18 degrees, the force P is applied at height h and the weight of the box is 36 lb Find: the maximum force P that can be applied without tipping the box. Assume that 1) the friction coefficient is high enough to prevent slipping and 2) the center of gravity of the box is at the box's geometric center. 6 feet, 0

A Chinook salmon can jump out of water with a speed of 6.70 m/s . How far horizontally ? can a Chinook salmon travel through the air if it leaves the water with an initial angle of ?=26.0° with respect to the horizontal? (Let the horizontal direction the fish travels be in the +? direction, and let the upward vertical direction be the +? direction. Neglect any effects due to air resistance.)
