Car traveling at a speed of 80km/h comes to a stop 5seconds after the driver applied brake. If the distance the car covers between the time the driver applied the brake until the time it comes to rest is 60 m then it's acceleration will be ?

How to change 1kg into cm ?

A spring has a spring constant of 50N/m. It is placed vertically and a 1kg mass is placed on top of it. The compression produced in the spring by this mass is?

A body of mass m1 standing on a smooth plane of ice throws a ball of mass m2 horizontally on the surface of ice. If x be the distance between them after a time t, then find the amount of work done by the boy in throwing the ball?

Suppose an object with initial acceleration of 10ft/s^2 is dropped from 300 ft. above the earth. How far would it travel in the first 2 seconds of its journey? Assume initial velocity is zero.

"Ken Ranfast is the star of the cross-country team. During the recent morning run, Ken averaged a speed of 5.8m/s for 12.9 minutes. Ken then averaged a speed of 6.10 m/s for 7.1 minutes. Determine the total distance which ken ran during his 20 minute jog."

sunil played a stroke and hits a ball with a velocity of 20 m/s at an angle of elevation 45 degree.kapil standing near the boundary along the line of stroke,50m away from the batsman,startsrunning to catch the ball at the instant the ball is hit.He managed to run at constant acceleration and at the last moment he took the catch 2 m above the level of the stroke point.Find
1.the acceleration with which kapil must have run.
2.velocity of the ball when caught by fielder
3.velocity of fielder while catching the ball.

please use the normal physics motion formula to solve so that i can understand and if u can give other problems related to this math , i will be grateful.thank you.

A batsman hits a ball at a velocity of 17.5 m/s angled at tan−1 (3/4) above the horizontal,
the ball initially being 60 cm above level ground. The ball is caught by a fielder standing
28 m from the batsman. Find the time taken for the ball to reach the fielder and the
height above ground at which he takes the catch.
