include a free body diagram. Be sure to label all forces with their agents and size. 1. A 5.0kg cat running along suddenly braces his furry feet on the slippery floot in order to stop. The cat experiences a deceleration of 2.0 m/s/s. how much frictional force acts on the cat 2. A 6.5 kg rock climber rappels down a rope with an acceleration of 0.50m/s/s. How much frictional force acts on the climber? 3.A 55kg create is pulled to the right with a force of 20N and is pushed to the right with a force of 10N. Friction provides a resistance force of 25N. If the crate stars from rest, how fast will it be moving after 2.0 seconds? (hint: first find the acceleration from the net force)
What friction torque is required to reduce angular speed
A flight attendant pulls her 69N flight bag a distance of 246m along a level airport floor at a constant velocity. The force she exerts is 37N at an angle of 58° above the horizontal. Find the coefficient of kinetic friction between flight bag and..
How much work did the movers do (horizontally) pushing a 150- crate 10.2 across a rough floor without acceleration, if an effective coefficient of friction was 0.50.
How several cubic meters of water are removed from storage under an area of 1 million square meters when the average head decline in this area is 2 meters.
Charge A and charge B are 2.5 m apart. Charge A is 1.4C and charge B is 2.5C. Charge C, which is 2.0 C, is situated between them and force on charge C is zero. How far from charge A is Charge C.
Define the frequency components of an AM signal and draw the AM signal for the given modulation index.
A computer is reading data from a rotating CD-ROM. At a point that is 0.030m from the center of the disk, centripetal acceleration is 120m/s2. What is the centripetal acceleration at a point that is 0.05 m from the center of disc.
find the potential difference across the capacitor. A conductor consists of a circular loop of radius R and two straight, long sections. The wire lies in the plane of the paper and carries a current I.
Find the coefficient of friction between ax and grindstone.Two negative point charges are separated by 20 rm cm and feel a mutual repulsive force of 3.35 mu N. The charge of one is three times that of the other. How much charge does each have.
A 12.00kg runaway grocery cart runs into a spring with spring constant 260-N/m and compresses it by 65 cm. What was the speed of the cart just before it hit spring.
A 1200-kg car travels at a constant speed of 18.00 m/s around a circular track that is 80m across. What is the kinetic energy of the car?
A highway curve with a radius of 550 m is banked properly for a car travelling 130 km/h. If a 1660- kg Porshe 928S rounds the curve at 250 km/h, how much sideways force should the tires exert against the road if the car does not skid.
