1. A car of mass 1,500 kg is traveling at a constant speed of 12 m/'s due north. What is its linear momentum? Force F (N) 2. The figure shows force versus time graph. (a) Calculate the impulse 200 0 0.2 0.4 0.6 Time t (s] (b) If this impulse was applied on a 3 kg mass at rest, what would its final velocity be? 3. A ball of mass 0.2 kg is thrown horizontally at a wall. If it hits the wall at 25 m/'s and bounces back with the same speed, what is the change in its momentum? 4. A ball of mass 0.2 kg is thrown horizontally at a wall. It hits the wall at 25 m/'s and bounces back in the opposite direction with a speed of 20 m/s. What is the magnitude of the change in its momentum?5. A ball of mass 0.2 kg is thrown horizontally at a wall. It hits the wall at 25 m/'s and bounces in the opposite direction with a speed of 20 m/s. If the collision lasted for 0.015 s, what is the magnitude of the impulsive force exerted on the ball? 6. A ball of mass 0.2 kg is thrown at an angle of 30 above the horizontal with a speed of 5 m/'s and travels as a projectile (a) What is the y-component of its momentum at the instant it is thrown? (b) At its maximum height, what is its momentum? 7. A rubber ball whose mass is 150 g is dropped from a height of 3.0 m onto a hard floor. The force-time graph of the impact is shown in the figure. How high does the ball bounce? 300 N- 8.00 ms
