A ball is thrown upward with a speed of 15 metre per second find the distance travelled by the ball in two second
Answers
Answer:
Let us take the point from which the ball is thrown up as origin and upward direction as positive and downward direction as negative.
The initial velocity u with which the ball is thrown up= 15m/s
The acceleration a acting on the ball = - 10m/s² ( negative sign as it is directed downward).
Time t = 2s.
Distance travelled can be obtained using the relation; s = u t + ½ a t². Substituting various values, we get,
s = 15m/s×2s - ½ ×10 m/s² × 2² s²= 30m - 5 m/s² ×4s² = 30m - 20m= 10m.
The distance travelled by the ball in first two seconds= 10m upwards from the point of projection.

Answer:
- Distance = 30m
Given:
- A Ball is thrown upward with a speed of 15 m/s
- Time = 2 seconds
To find:
- The distance travelled by the ball in two seconds
Solution:
We know that :
Given :
- Speed = 15 m/s
- Time = 2 seconds
By substituting the given values, we get :
[ By substituting the values ]
