Question

A truck is moving on a straight road with uniform acceleration.the following table gives the speed of the truck at various instants of time Speed(m/s) 5 10 15 20 25 30 Time(s) 0 10 20 30 40 5​ Determine from it : i)the acceleration of truck ii)the distance travelled by truck 2.a car starts from rest and rolls down a hill with constant acceleratation.it travels a distance of 800 m in 10 s.find its acceleration.also, find the force acting on it if its mass is 800 kg 3.A scooter is moving with a velocity of 25m/s and it takes 5s to stop after the brakes are applied. if the mass of the scooter along with the rider is 180kg, find the change in momentum in this case

Answer 1

1st question answer
accelerate -0.5m\s²
distance-875m
2nd question
acceleration-16m\s²
force12800n
3rd question
900 is change in momentum
