The acceleration of a bus is given by ax(t)=?t, where ? = 1.26m/s3 is a constant.
A) If the bus's velocity at time t1 = 1.12s is 5.09m/s , what is its velocity at time t2 = 2.13s?
B) If the bus's position at time t1 = 1.12s is 6.01m , what is its position at time t2 = 2.13s?
A baseball pitcher throws a fastball at a speed of 45.00m/s. The acceleration occurs as the pitcher holds the ball in his hand and moves it throughout an almost straight-line distance of 4.0 m. compute the acceleration; assume that it is constant ..
A horizontal pipe contains water at a pressure of 150 {rm kPa} flowing with a speed of 1.30 {rm m/s}. The pipe narrows to one-half its original diameter. What is the speed of the water.
At each of the designated points, rotate the given vector to indicate the direction of the force exerted by the water on either the inside of fishbowl (for points A and B) or the outside of the goldfish (for points C, D, and E).
Suppose that all movement occurs in a straight line up and down along the y axis. Find out the muzzle velocity of the ball (i.e., the velocity of the ball at spring's equilibrium position).
Lightning As a crude model for lightning, consider the ground to be one plate of a parallel-plate capacitor and a cloud at an altitude of 680m to be the other plate.
The distance between deer B and C is 92 m. What is distance between deer A and C.
Three 15.53-g Styrofoam balls of radius 2 cm are coated with carbon black to make them conducting and then are tied to 1.15-m-long threads and suspended freely from a common point
An electronics technician wishes to construct a parallel-plate capacitor using rutile (? = 1.00 102) as the dielectric. If the cross-sectional area of the plates is 1.00 cm2, what is the capacitance if the rutile thickness is 1.00 mm?
One mole of an ideal gas is heated so that T = AP2, where A is a constant and P is the pressure. The temperature changes from T0 to 4T0. Find out the work completed by the gas. (Use the following as necessary: T0, P0, and V0.)
