Problem#4: Calculate an object’s acceleration when ? = 100 ? and when ? = 175 ?. Refer to the v-s graph below. Problem#5: As a vehicle leaves the first point, it gains a speed at the rate of 4 ??/? 2 for 6 ? and then at the rate of 6 ??/? 2 until it has reached the speed of 48 ??/?. The vehicle maintains the same speed until it approaches the second point; brakes are then applied and the vehicle slows down constantly until it stops in 6 ?. The total running time from first point to second point is 40 ?. Plot the a−t, v−t, and x−t graphs, and calculate the distance between the first and second point. Problem#4: Calculate an object's acceleration whens = 100 m and whens = 175 m.Refer to the v-s graph below.(m/s)50-s (m)150200Problem#5: As a vehicle leaves the first point, it gains a speed atthe rate of4 ft/s? for 6 s and then atthe rate of 6 ft/s² until it has reached the speed of48 ft/s. The vehicle maintains the same speed until it approaches the second point;brakes are then applied and the vehicle slows down constantly until it stops in6 s. The total running time from first point to second point is 40 s. Plot the a-t,v-t,and x-t graphs, and calculate the distance between the first and secondpoint.
