good chance it is motor/transmissiom mounts. open hood, have friend start engine, have friend accelerate on and off several times, look to see if engine has noticable movement compare to another car with same engine/transmission configuration if movement is considerable consider mounts. don't let this go long Jim
If a car shakes during acceleration the brake rotors may be damaged. If the rotors are damaged they will be unstable as the tires rotates making the whole car shake.
The pistons are running in the cylinders of the engine, so when the rpm of the engine rises, the pistons quickley build up speed. It is this rapid acceleration of the pistons that casue the car to shake.
might have misaligned or loose wheels
If your car shakes while accelerating check your motor mounts. Then check your transmission.
Will not move, shake on acceleration, or a popping noise during turns.
Warped rotor and worn out brake pads.
Assuming this is a front wheel drive vehicle, a CV joint in one of the halfshafts is going bad.
The car's acceleration between 25s and 30s can be calculated by determining the change in velocity during that time interval and dividing it by the time elapsed. Acceleration = (final velocity - initial velocity) / time. You need to know the initial and final velocities of the car during that time period to calculate its acceleration.
could be the engine mounts. could because of early detonation, which could be caused by overheating. it also could be a rod knock, which is more likely if it keeps shaking during acceleration and higher rpm's. first thing to check would be if its too hot, watch the temp guage, and make sure it doesnt get too high.
The velocity of a car during braking with constant acceleration can be calculated using the kinematic equation: final velocity = initial velocity + acceleration * time. As the car brakes, the initial velocity decreases to 0 m/s (assuming the car comes to a stop), and the acceleration due to braking is negative. Therefore, the equation becomes: final velocity = -acceleration * time.
The acceleration of the car would be determined by dividing the change in velocity by the time taken. If the car started from rest and reached a speed of 30 m/s over 5 seconds, the acceleration would be 6 m/s^2.
The car will idle rough and hesitate during acceleration.
