- On an alien planet, an object moving at 4.0 m/s on the horizontal ground comes to rest after traveling a distance of 10 m. If the coefficient of kinetic friction between the object and the surface is 0.20, what is the value of g on that planet?arrow_forwardIf a block of mass m lies on a wedge of mass M, here all surfaces are smooth, and the block slips on the wedge, will the wedge have any acceleration? If yes, explain why and of what magnitude?arrow_forwardAssuming an unbanked curve, find the minimum static coefficient of friction, between the tires and the road, static friction being the reason that keeps the car from slippingarrow_forward

The block lies on frictionless incline of angle 30 . Find the magnitude of the acceleration of the two objects and the tension in the cord Take g = 9.8 ms : 12 kgarrow_forwardAs shown below, the mass of block 1 is m1 = 4.0 kg, while the mass of block 2 is m2 = 8.0 kg. The coefficient of friction between m1 and the inclined surface is μk = 0.40. What is the acceleration of the system?arrow_forwardIn a soccer match against Mexico in 2014, US Women’s National Team striker Alex Morgan scored a sweetheaded goal in the 79th minute of the game. Just as the ball left her head, the horizontal component of its acceleration was 225 m/s , and the vertical component of its acceleration was -200 m/s (assuming thepositive direction points up). If the ball has a mass of 425 g, what was the magnitude and direction of theforce she applied to the ball? Note- you can ignore the weight of the ball.arrow_forward

At the very top of his arc, a 55 kg vaulter is moving at 2.5 m/s and is 5.1 m from the bottom end of the pole. What vertical force does the pole exert on the vaulter?arrow_forward
- A block of mass m2 on a rough, horizontal surface is connected to a ball of mass m1 by a lightweight cord over a lightweight, frictionless pulley as shown in 5.21a. A force of magnitude F at an angle θ with the horizontal is applied to the block as shown, and the block slides to the right. The coefficient ofkinetic friction between the block and surface is μk.

The bicyclist has a frontal area of 0.45 m2and a dragcoefficient of 1.1 in the upright position, and a frontal area of 0.4 m2and a dragcoefficient of 0.9 in a racing position. If the downhill speed of the bicyclist(terminal velocity) can be determined when the total force acting on the “body” inthe direction of movement is equal to zero, determine the percentage of downspeed that she can be increased when she is in a racing position.
