Velocity, displacement?
Please help me to solve this! I have no idea!
The brakes of a car failed and the car travels at a constant velocity of 45 m/s off a 27 m cliff.
A) How far from the cliff does the car hit the ground?
B)When it hits the ground, it skids off 13 m/s with a...
Conservation of momentum! help please!?
A m1 = 0.450 kg block is released from rest at the top of a frictionless track h1 = 2.85 m above the top of a table. It then collides elastically with a 1.00 kg mass that is initially at rest on the table, as shown in Figure P6.47.
Figure P6.47...
A 2.3 103 kg car starts from rest and accelerates along a horizontal roadway to +17 m/s in 21 s. Assume that air resistance remains constant at -500 N during this time. Find
(a) the average power developed by the engine and
(b) the instantaneous power developed at t = 15 s.
I am...
Two identical massless springs of constant k = 200 N/m are fixed at opposite ends of a level track, as shown in Figure P5.62. A 5.90 kg block is pressed against the left spring, compressing it by 0.150 m. The block (initially at rest) is then released, as shown in Figure P5.62a. The entire track...
HI guys, I am having a lot of trouble with determining initial velocity, x and y components etc. Can someone please help me with this
Sara drives a rocket sled from rest 25 m up a 15 degree ramp at an acceleration of 8 m/s2. Whats the final velocity?
Thank you
Ronson drives a rocket sled from rest 25 m up from a15 degree ramp at an acceleration of 8.0 m/s2. The rocket cuts off at the end of the ramp, which happens to be atthe edge of a 75 m high cliff. He freefalls in his sled until he bounces on a trampoline, which is on a 30.0 m high platform, and...
