Spare) A car with mass m is poised at the top of a frictionless track as shown in the figure. Assume a point mass for the car. (a) Find the tangential velocity of the car at a position of the circular track (making an2r angleの. (b) Find the position at which the car falls off the circular track in terms of e (c) Find the condition for the car to reach the top (point C) of the circular track
4) A 100 gram toy car is propelled by a compressed spring, as shown in the figure. The car tollows a track that ries 18 cm above the starting point. The toy car is released from the spring with a speed of energy of the car when the car is released from spring: tb) kinetic energy of thea 5m/s., find (a) the kinetic the to of the sope. speed of the car at the top of the slope. Path of...
3. A freight car moves along a frictionless level railroad track at constant speed. The car is open on top. A large load of coal is suddenly dumped into the car. What happens to the velocity of the car? A) It increases. B) It remains the same. C) It decreases D) cannot be determined from the information given
2. A toy car with a mass of 35g (0.035kg) is moving clockwise around a loop-the-loop (a track in the shape of a circle that causes the toy car to travel along a circular trajectory) with a radius of R- 13cm (0.13m) as depicted in the diagram below. At the point shown (the - on the diagram below) its instantaneous speed (the magnitude of its velocity) is 1.5m/s and its speed is increasing at a rate of 7.1m/s2. (a) (4...
Please show all work 2. In the figure, a stunt car driver negotiates the frictionless track shown in such a way that the car is barely in contact with the track at the top of the loop. The radius of the track is 9.9 m and the mass of the car is 1800 kg. Find the magnitude of the force of the car on the track when the car is at point A. You can treat the car as a...
Consider a frictionless track as shown in the figure below. A block of mass m1 = 5.65 kg is released from A. It makes a head-on elastic collision at B with a block of mass m2 = 20.0 kg that is initially at rest. Calculate the maximum height to which m1 rises after the collision.Two masses are shown on a frictionless wooden track. The left part of the track curves downward from left to right, starting from an almost-vertical slope and then decreasing in...
A child operates a remote controlled toy car on a linear track. The figure below plots the car's position as a function of time. x (m) Find the velocity of the toy car at the following times. Indicate the direction with the sign of your answer. (a) t 1.4 s: 1.4 Remember that velocity is the change in position per the change in time. If the graph plots position vs. time, what property of the plot in each segment is...
