Step 1
Step 1: Identify the given values: - Initial velocity, \( v_i = 30 \, \text{m/s} \) [E] - Final velocity, \( v_f = 0 \, \text{m/s} \) - Time, \( \Delta t = 15 \, \text{s} \) - Mass of the car, \( m = 2500 \, \text{kg} \) Show more…

3. (a) A 350 g model rocket accelerates at 45.9 m/s/s on takeoff. Determine the upward force experienced by the rocket. (b) If acceleration of the rocket is reduced to 20 m/s^2, then what would be the force? 4. If a car accelerates from zero to 25 m/s in 30 sec, (a) what is its acceleration and (b) how much force it has applied if its mass is 800 kg? 5. (a) If your mass is 60 kg, what is your weight on Earth, Moon and Jupiter if gravity on Earth is 9.8 m/s^2, on Moon is 1.62 m/s^2, on Jupiter is 24.8 m/s^2? (b) What will be your mass on these planets? 6. Henry is dragging a bag of grass from the garage to the street on the evening before garbage pick-up. Use the free body diagram to show all forces working on it. Then find (a) how much force is working as weight of the bag with grass if the mass of the bag with grass is 5 kg, (b) how much normal force acting on bag, (c) if applied force on it is 45 N and frinction force is 5 N, then how net force acting upon the bag, (d) What would be acceleration of the bag? 7. A 1370 kg car is skidding to a stop along a horizontal surface. The car decelerates from 25 m/s to a rest position in 2.0 seconds. Assuming negligible air resistance determine (a) how much force is applied by the brake to stop? (b) if this force is equal to the friction force, find coefficient of friction between the car tires and the road surface. (c) what is the weight of the car? 8. Hanley is pulling on a rope to drag his backpack to school across the ice. He pulls upwards and rightwards with a force of 22.9 N at an angle of 35 degrees above

A 0.4 kg object is attached to a spring with a spring constant 158 N/m so that the object is allowed to move on a horizontal frictionless surface. The object is released from rest when the spring is compressed 0.16 m. Find the force on the object when it is released. Answer in units of N. What is the acceleration at this instant? Answer in units of m/s 2 .
