Problem: A car has a mass of 1500 kg. If the driver applies the brakes while on a gravel road, the maximum friction force that the tires can provide without skidding is about 7000 N.
Problem: If the car is moving at 29 m/s, what is the shortest distance in which the car can stop safely?
I don't know how to get that answer for the above problem. Please help! Thanks.
find coefficient of kinetic friction between m1 and shelf.
A uniform stick 1.5 m long with a totalmass of 300 g is pivoted at its center. A 3.5 g bullet is shot through the stick midway betweenthe pivot and one end (see figure). The bullet approaches at 250m/s and leaves at 160 m/s.
An electric vehicle starts from rest and accelerates at a rate of2.6 m/s2 in a straight lineuntil it reaches a speed of 20 m/s. The vehicle then slows at a constant rate of 1.0 m/s2 untilit stops. How much time elapses from start tostop?
