Question: A physicist s car has a small lead weight suspended from
A physicist’s car has a small lead weight suspended from a string attached to the interior ceiling. Starting from rest, after a fraction of a second the car accelerates at a steady rate for about 10 s. During that time, the string (with the weight on the end of it) makes a back-ward (opposite the acceleration) angle of from the vertical. Determine the car’s (and the weight’s) acceleration during the 10-s interval.
Answer to relevant QuestionsConsider a 2.0-kg ball and a 6.0-kg ball in free fall. (a) What is the net force acting on each? (b) What is the acceleration of each? A horizontal force of 40 N acting on a block on a frictionless, level surface produces an acceleration of 2.5 m/s2. A second block, with a mass of 4.0 kg, is dropped onto the first. What is the magnitude of the acceleration ...In the frictionless apparatus shown in Fig. 4.43, m1 = 2.0 kg. What is m2 if both masses are at rest? How about if both masses are moving at constant velocity? A hockey player hits a puck with his stick, giving the puck an initial speed of 5.0 m/s. If the puck slows uniformly and comes to rest in a distance of 20 m, what is the coefficient of kinetic friction between the ice and ...In the apparatus shown in Fig. 4.46, m1 = 10 kg and the coefficients of static and kinetic friction between m1 and the table are 0.60 and 0.40, respectively. (a) What mass of m2 will just barely set the system in motion? ...
