Question

A 1400kg car is rolling at 1.9m/s . You would like to stop the car by firing a 10kg blob of sticky clay at it.

1) How fast should you fire the clay?

Express your answer to two significant figures and include the appropriate units

Answer 1

A 500gcart is released from rest 1.00 m from the bottom of frictionless 30 deg ramp.?
The cart rolls down the ramp and bounces off a rubber block at the bottom. The figure shows the force during the collision. The cart rolls down the ramp and bounces off a rubber block at the bottom. The figure shows the force during the collision. Max at 200 N during time interval of 26.7 ms
After the cart bounces, how far does it roll back up the ramp?


When the cart initially this the rubber block, the force exerted by the rubber (elastic) block = 0 N
The Maximum force = 200 N
Average force =
