Q. A 25g ball is fired with an initial speed v1 toward a 150g ball that is hanging motionless from a 1.30m string. The balls have a perfectly elastic collision. As a result, 150 g ball swings out until the string makes an angle of 37° with vertical. What was v1?
Q. A fighter pilot flying with a speed of 500•m/s (about Mach 1.5) makes a turn with a radius of 5250•m. What centripetal acceleration does pilot experience? Express your answer in g's (multiples of 10•m/s2).
Object A, which has been charged to + 29.2 nC, is at the origin. Object B, which has been charged to - 28.9 nC, is at ( x,y ) = ( 0.0;{rm cm},; 1.50 cm ).What is the y-component of force (vec{F}_{rm A ; on ; B})_{rm y} on B due to A.
A mass of 1.60 kg stretches a vertical spring 0.335 m. If the spring is stretched an additional 0.164 m and released, how long does it take to reach the (new) equilibrium position again.
An "energy bar" contains 21g of carbohydrates. If the energy bar was his only fuel, how far could a 68 kg person walk at 5km/hr? Express your answer using two significant figures.
How much energy must be added to a bowl of 125 popcorn kernels in order for them to reach a popping temperature of 175celsious? assume that their initial temperature is 21 celsious, that specific heat capacity of popcorn is 1650 j/kgcelsious, and ..
A paratrooper pilot fell 360 m after jumping without his parachute opening. He landed in a snow bank, creating a crater 1.50 m deep, but survived with only minor injuries. Assume the pilot's mass was 80 kg and his terminal velocity was 50 m/s.
Two boats start together and race across a 56km wide lake and back. Boat A goes across at 56 km/h and returns at 56km/h. Boat B goes across at 28km/h, and its crew, realize how far behind it is getting.
Make a 10 to12 slide powerpoint presentation on behaviourism and social-learning theory. Include speaker notes and graphics, limit text to fie lines, and use approximately five words per bulleted item.
Billiard ball A of mass = 0.130 moving with speed = 2.80 strikes ball B, initially at rest, of mass = 0.150. Consequently of the collision, ball A is deflected off at an angle of 28.0 with the speed = 2.00.
Find out an angle of the velocity vector
A 4.22 box sits at rest at the bottom of a ramp that is 7.74 long and that is inclined at 40.0 above the horizontal. The coefficient of kinetic friction is 0.40, and the coefficient of static friction is 0.50.
A penny sits on a rotating disk that rotates once every 0.9 s. The coefficients of static and kinetic friction between the penny and disk are 0.58 and 0.48, respectively. For the penny to not slide, what is its largest distance from the center of the..
