A constant F is applied to a mass m intially heading east with v intial until velocity is negative inital the time is 2t what the total distance?



First half of movement.... velocity goes from v to 0
Time = t, mass = m, v goes to 0
Impulse = Ft = m(v - 0) = mat (Momentum is Impluse)
a = v/t
One way distance = vt - 1/2(v/t)(t^2)
= vt - vt/2 = vt/2
Two way distance = 2(vt/2) = vt

2. A halfback, with a mass of 95kg abd moving at 4.1m/s, on an apparent breakaway for a touchdown is tackled from behind by a cornerback whose mass is 85kg running at 5.5 m/s in the same direction. What was their mutual speed immediately after the touchdown-saving tackle?

3. A 9500kg boxcar traveling at 16 m/s strikes a second car. The two stck together and move at a speed of 6 m/s. What is the mass of the second car?

4. A 15g bullet strikes and becomes embedded in a 1.1 kg block of woob placed on a horizontal surface just in front of the gun. If the coefficient of kinetic friction between the block and the surface is 0.25 and the impact drives the block a distance of 9.5m before it comes to rest, what was the muzzle speed of the bullet?
