A car is moving with a constant aeceleration along a straight level road. The car is observed to cover two consecutive 450 m stretches in 20 scconds and 10 seconds respectively. Find 6. (a) the acceleration of the car, (b) velocity of the car 3 seconds before it entered the first stretch. At the end of the second stretch, the car is subjected to a retardation of magnitude 2r ms-2, where r is the distance of the car from the end of the second stretch. Find the further distance travelled by the car before coming to rest. CO

A 0.150 kg lump of clay is dropped from a height of 1.75 m onto the floor. It sticks to the floor and does not bounce. What is the magnitude of the impulse J imparted to the clay by the floor during the impact? Assume that the acceleration due to gravity is g = 9.81 m/s². J = The force exerted by the floor on the clay is plotted as a function of time in the figure. What must have been the maximum force Fmax exerted by the floor on the clay? Fmax kg. m/s = N Force (N) F max 0 F 7.5 ms Time (ms)
