A car starts from rest & acquire a velocity of 54km/h in 2 sec. Find- a) the acceleration
b) distance traveled by car assume motion of car is uniform
c) if the mass of the car is 1000kg. what is the force acting on it?
Pls help me. I'm bad in this subject. kinda need it by today​

a. Acceleration, a = 7.5 m/s

b. Distance, S = 15 meters

c. Force = 7500 Newton

Explanation:

Given the following data;

Mass = 1000 kg

Initial velocity = 0 m/s (since it's starting from rest).

Final velocity = 54 km/h

Time = 2 secs

Conversion:

54 km/h to m/s = 54*1000/3600 = 15 m/s

a. To find the following acceleration;

Mathematically, acceleration is given by the equation;

Substituting into the formula, we have;

Acceleration, a = 7.5 m/s

b. To find the distance, we would use the second equation of motion.

Where;

Substituting into the equation, we have;

Distance, S = 15 meters

c. To find the force, we would use the following formula;

Force = 7500 Newton

the independent variable, the one that is intentionally manipulated, is whether or not the car hits the barrier.

the dependent variable, the one that you measure the response in, is the distance that the washers travel.

dec 23, 2016 - a load of bricks weighing 680 n a distance of 10 m across a parking lot. if if the worker pushes the cart with a constant force of 209 n, what work= force x distance = 220 n x 10 m = 2200 n.m = 2200 j i don't know where the person got it from, but the initial part, work= force x distance me.
