Q. A car carrying a 75-kg test dummy crashes into a wall at 25 m/s and is brought to rest in 0.1 s. Show that the average force exerted by the seat belt on the dummy is 18, 750 N.
Q. The solution for has a singularity (that is, becomes infinitely large) at a certain angle . For any angle , the expression for will be negative. However, a negative applied force would reverse the direction of friction acting on the lawnmower, and thus this is not a physically acceptable solution. In fact, the increased normal force at these large angles makes the force of friction too large to move the lawnmower at all.
A compound microscope has an objective lens of focal length 10.50 with an eyepiece of focal length 14.80, and it produces its final image at infinity. The object to be viewed is placed 2.00 beyond the focal point of objective lens.
