A car of mass 875 kg is traveling 30.0 m/s when the driver applies the brakes, which lock the wheels. The car skids for 5.60 s in the positive -direction before coming to rest. (a) What is the car's acceleration? (b) What magnitude force acted on the car during this time? (c) How far did the car travel? [Ans: ()-536 m/s (b) 4690 N(c) 84,0 m]
A car of mass 772 kg is traveling 24.4 m/s when the driver applies the brakes, which lock the wheels. The car skids for 5.27 s in the positive x-direction before coming to rest. a). What is the car's acceleration (in m/s2)? (Indicate the direction with the sign of your answer.) b). What magnitude force (in N) acted on the car during this time? c). How far (in m) did the car travel?
1) Tyrion is pulling a 30 kg sled loaded with ale across an ice lake. Assume the sled starts from rest and that it moves a distance of 10 m to the right. He pulls the sled to the right with a force of 300 N at angle of 30° above the horizontal. Once again, Cersei is trying to stop Tyrion from leaving and pulls on the sled horizontally to the left with a force of 100 N. Find the...
1. A bullet of mass m -25.0 g is fired into a stationary block of mass m, -4.00 kg, which is suspended on a rope, as shown below. The bullet is initially traveling with velocity v. - 400 m/s, passes through the block and emerges with a final velocity horizontally Immediately after the impact the block travels upward with a velocity of 2.00 m's and reaches a vertical height, h before coming to rest. Determine the maximum height the block...
So I know there is 4 different equationsfor kinematics. Can you pick the problems that use each one and write out how you do it? Especially 6 and 10 because those seem very hard. 1-D Kinematics Practice PHYS&114 Name: 1. A car starting from rest travels 231 m with a constant acceleration of 1.05 3. What is its 2. How far does a train travel while its velocity changes from +102 to +45.0 등 in 22.0 seconds? 3. You sprint...
in this lab we will drop a steel ball P steel=8000 kg/m^3, r ball=2.18x10^-3) through the air (nair=1.8x10^-5 Pas, P air= 1.29kg/m^3) and through a viscous soap solution (n soap ~ 9.0 Pa s) you will measure this number in lab, but use this number for prelab.( P soap = 1000kg/m^3) 1Pa= 1N/m 1. (a) assuming that the ball falling through the soap solution experiences visocus drag, find the terminal speed of the ball, the speed at which the weight...
A 20 kg mass starts at rest and has two forces acting on it: F1 & F2. F1 = (13.0 N,32.0 N) and F2 = (-32.0 N.-13.0 N). How far does this object travel after 9 seconds? Report you answer to the nearest meter.
A block of mass 3 kg is pushed against a spring of spring constant 3000 N/m. Initially, the spring is compressed by a distance of 0.220 m, when the block is released from rest and travels along a horizontal frictionless surface before encountering a frictionless ramp, inclined at an angle of 37° above the horizontal. How far along the ramp does the block travel before momentarily coming to rest?
