A car travels in a straight line along a road. Its distance x from a stop sign is given as a function of time t by the equation 𝑥 = 2.0𝑡2 − 0.50𝑡3. Calculate the distance of the car when it achieves its maximum speed in the positive x direction.
If 2trains 18km apart are traveling towards each other 1 with a velocity of 35m/s & the other moving at 25m/s, how long would it be before the trains pass by each other?
A truck pulls two trailers, coupled together by a strong trailer hitch. It starts from rest and accelerates to 0.31 m / s2 forward on a straight road. The mass of the truck is 5325 kg, the mass of the first trailer is 28,205 kg, and the mass of the second trailer is 22,045 kg. Calculates the strength of the tension on the hitch between the truck and the first trailer, and the tension between the first and second trailer.If 2trains 18km apart are traveling towards each other 1 with a velocity of 35m/s & the other moving at 25m/s, how long would it be before the trains pass by each other?
Briefly explain how you could resolve vectors into two components that are at right angles.
Demonstrate your understanding of the following through reference to the relevant authors and the findings from their research.
• Newton’s Laws of Motion.
• Ideal gas laws.
• You must apply both of these to a range of physical situations by giving appropriate examples.
What is the final velocity of a 1200 kilogram car starting from rest after 50 meters when 4500 Newton's of force is applied?
How fast is a 10 kg box going to be moving from rest after 3 seconds if a 200 N force is applied to the left and a 50 N force is applied to the right?
what is the flight time of a cannon fires a cannonball with a muzzle velocity of 50.0 m/sec at an angle of 40 degrees.
Two stations A and B are 10 km apart in a straight track, and a train starts from A and comes to rest at B. For three quarters of the distance, the train is uniformly accelerated and for the remainder distance uniformly retarded. If it takes 15 minutes over the whole journey, find its acceleration, retardation and the maximum speed it attains.
