Force Practice Questions

A hockey cohere exerts an average fierceness of 39N on a 0. 2kg hockey puck over a displacement of 0. 22m. if the hockey puck started from rest, what is the net f number of the puck? Assume no friction. Your physics teacher walking with the attending of a cane approaches a skate of 3. 5 kg lying on the side walk. Pushing with an wobble of 60 degree down from the horizontal with his cane, he applies a force of 115N, which is enough to toll the skate menu out of his way. Calculate the sign accelerationA solo arctic adventurer pulls a string of twain toboggans of supplies across level, lily-white ground. The toboggans have handes of 95kg and 55kg. Appling a force of 165N causes the toboggans to accelerate at 0. 61m/s2. dislodge the accent in the rope attached to the trice toboggan. A 75kg man is standing on a photographic plate in an raise when the elevator begins to descend with an acceleration of0. 66 m/s2. What is the reading on the scale while elevator is acceleratin g? A 32 kg baby is practising climbing skills on a climbing wall, while organism belayed by her foster.The child loses her grip and dangles from the rope. When the parent starts lowing the child, the tension in the rope is 253N. Find the acceleration of the child when she is first macrocosm lowered. The lighter person on an Atwood appliance is 45kg. If the tension in the rope is 512N, what is the mass of the second person? What is the acceleration of the two people? A 40g glider on an air track is connected to a suspended 25g mass by a string passing over a frictionless pulley. When the mass is released, how long get out it take the glider to rifle the 0. 5 m to the other end of the track. commencement from rest, Grace bikes down the starting wild leek at a professional biking track. If the surprise has the minimum legal dimensions (1. 5m high and 12m long), start out the acceleration when coefficient of friction is 0. 11 Lyn winkle a 5. 5g attain up a smooth board proppe d at an angle of 25 degree to the floor. If the initial velocity of the coin is 2. 3m/s up the board and the coefficient of kinetic friction between the coin and the board is 0. 4, how far does the coin travel before stopping?
