You are installing a new spark plug in your car, and the manual specifies that it be tightened to a torque that has a magnitude of54 N·m. Using the data in the figure, determine the magnitude F of the force that you must exert on the wrench.
A dog trots 3.6 meters east and 5.0 meters north. What are the magnitude and direction of the dog's displacement with respect to the original position.
A 0.940 kg block slides on a frictionless horizontal surface with aspeed of 1.70 m/s. The bock encounters an unstretched springwith a force constant of 260 N/m. Find the total time ofcontact with the spring before the block comes to rest.
A man holds a 190 N ball in his hand, with the forearm horizontal. Find magnitude and direction of the force applied by the upper arm bone to the forearm at the elbow joint
A comet with a mass of 7.75 1011 kg strikes Earth at a speed of 26 km/s. Find the kinetic energy of the comet in joules

q1. a car at the indianapolis-500 accelerates uniformly from the pit area going from rest to 325 kmh in a semicircular
A car of mass 960 travels at a speed of 30 along the straight road. The driver sees a red traffic light ahead, and applies brakes. The coefficient of friction between the car tyres and the road is 0.88. Take the acceleration due to gravity to be 9.80..
After catching the ball, Sarah throws it back to Julie. However, Sarah throws it too hard so it is over Julie's head when it reaches Julie's horizontal position. What is the speed of the ball when it leaves Sarah's hand
