chapter-force solve the following . 1.A car starts moving from rest . If it gains a velocity of 9km/hr after 10 seconds , what is the acceleration of the car? ans should be- 2m/s sq please answer it fast. if you answered correctly i will follow and thanks you and mark you brainalist and give more points.donot spam.if you spam you will be reported.

Explanation:
Multiply the time by the acceleration due to gravity to find the velocity when the object hits the ground. If it takes 9.9 seconds for the object to hit the ground, its velocity is (1.01 s)*(9.8 m/s^2), or 9.9 m/s.It is also commonly abbreviated as ms−2. For example, if the velocity of a particle moving in a straight line changes uniformly (at a constant rate of change) from 2 m/s to 5 m/s over one second, then its constant acceleration is 3 m/s2.Terms in this set (24) Does a car accelerate when it goes around a corner at a constant speed? Yes, because its direction is changing. Acceleration occurs whenever there is a change in speed, direction, or both.Answer. Falling object is influence by acceleration due to gravity which is 9.8 m/s². This means that in every one second the change in velocity is 9.8 m/s and the velocity increases by 9.8 m/s every second. So after one second, the acceleration of the ball is 9.8 m/s² and its velocity is 9.8 m/s.
Answer:
584m is the correct ans.
