QUESTION6 Traveling with an initial speed of vo 53 km/h, a car accelerates at 3,259 km/h2 along a straight road. What would be the distance traveled (in meters) to reach a final speed for the car to reach a final speed v 106 km hr? QUESTION7 The velocity of a particle is v = 2.1/ + (3-20 j mis, where t is in seconds. Ifrs 0 when t = o, determine the displacement of the particle in the x direction...
Two cars have a race. Car A drives with constant speed of 20 m/s. Car B drives with speed 10 m/s for 1 s, then accelerates uniformly to a speed of 20 m/s during the next 3 s. Has Car B caught Car A after the 4 seconds pass?
A bus starts from rest and accelerates uniformly for 20 seconds to a speed of 18 km/h. It then moves with a uniform velocity and it is finally brought to rest in 100 meteres with a constant retardation. If the total distance travelled is 0.5km. Find the accelration, retartdation and total time taken. My answers are total time = 110s Retardation -1/4ms^-2. Please check if they r correct or not!!!
A car on a straight level road, starts from rest and accelerates to a speed of 1,846 ft/'s in 49 seconds. What is the car's average acceleration in ft/s??
Prob. 2 A car starts from rest, accelerates at 1.5 m/s, and reaches a maximum speed vi. After that it decelerates at 2 m/s until it stops. During the entire process the car has traveled a distance of I km. (a) Sketch the velocity diagram of the particle during the process. (Leave vI as an unknown on the diagram) (b) Determine the maximum speed vi. (e) Determine the total time required.
QUESTION 6 1.5 initial speed of vo 53 km/h, a car accelerates at 3,259 km/h along a straight road. What would be the distance traveled (n meters) to reach a final speed for the car to reach a final speed vy-106 km/hr?
A test car starts from rest on a horizontal circular track of 80 m radius and increase its speed at a uniform rate to reach 100 Km/h in 10 seconds. Determine the magnitude of total acceleration of the car 8 seconds after the start . Rotation of the radially slotted arm is governed by 0-0.21 + 0.02r, where 0 is in radians and t is in seconds. Simultaneously, the power screw in the arm engages the slider B and controls...
Consider a 2100-kg car cruising at a constant speed of 70 km/h. Now, the car starts to pass another car by accelerating to 110 km/h in 12 s. Determine the additional power needed to achieve this acceleration. What would your answer be if the total mass of the car were only 700 kg?
4. A particle is moving along a straight line through a fluid medium such that its speed is measured as v (2t) m/s, where t is in seconds. If it is released from rest at s 0 determine its positions and acceleration when t 3 s. a) s 2 m, a 9 m/s2 c) S 18 m, a 2 m/s2 d) s 2 m, a 18 m/s2 5. A driver accelerates at a rate of a(S)-0.2 S. If the driver...
QUESTION 5 58 km/h, a car accelerates at 3,901 km/h2 along a straight road How lon will i take (in seconds) of vo Traveling with an initial speed of vo 58 kmh, a car accelerates at 3,901 km/h2 along a straight road for the car to reach a final speed vf 101 km/hr?
