Question 6 (motion to force) A 1000 kg car with you in it accelerates from rest to 32 m/s in a time of 4 seconds. You are 50 kg. a. With how much force does the ground push the car forward? b. With how much force does the seat push you forward?
3. An engine exerts a force of 10000 N on a 1000 kg car travelling over a flat road. The force (overcoming friction) accelerates the car from rest such that it travels a distance of 50 m in 5 s Find e. the net acceleration of the car, f. normal force exerted by the road on the car, and g. the coefficient of kinetic friction between the car and the road? 4. A 10 kg block is initially at rest...
A car accelerates from rest at S m/s for 5 seconds. It moves with a constant velocity for 15 seconds, and then decelerates at 5 m/s to come to rest in 5 seconds. The entire journey takes 25 seconds. Plot the velocity-time graph of the motion AND determine the total distance the car travelled. (10 pts.) 4.
