Calculate the average speed of students of your class we who have participated in 100 metres and 200 metres running race write a report

A car is moving in a straight line. The car covers 110 meters in 10 seconds and then it covers 140 meters in 10 seconds. If the acceleration is constant.
Find the initial speed of the car and the acceleration

Wind blowing from south at 10m/s but to a cyclist it appears to be blowing from the east at 10m/s . The cyclist has a velocity and direction

The acceleration of a point is given by a=5-t^2. write an equation for velocity if v=4 m/s when t=3 s

A constant torque of 200N turns a wheel about its centre, the moment of inertia about this axis is 100kilogram meter square. Find the kinetic energy gained in 20 revolutions

A 10 pesos is dropped from the top the building. Calculate the position and the velocity of the coin after 1 second.

is the bugs acceleration constant?

The points A,B and C lie on the same straight line, the distance between AB being 60m. A particle crosses the point A with the velocity 2m/s and moves with uniform acceleration along the straight line. After crossing the point B, it takes 10 sec to reach C with velocity 5m/s. Find the acceleration of the particle.

A car starting from rest accelerates at the rate of f through distance S then continues at constant speed for tome t and decelerates at the rate f/2 to come to rest .if total distance travelled is 15s then S

A retarding force f=-2v is acting on a body of mass 10 gram. Find out time taken for its velocity to reduce to 37% of its initial value if initial velocity is 1m/s
